Configuring Internet Addressing
By default, GroupWise®uses a proprietary address format consisting of a user’s ID, post office, and
domain (userID.post_office.domain). However, when you install the GroupWise Internet Agent,
GroupWise also supports native Internet-style addressing consisting of a username and Internet
domain name (for example, userID@Internet_domain_name).
Internet-style addressing is the preferred addressing format if you are connected to the Internet,
because with Internet-style addressing, users have the same address within the GroupWise system as
they do outside the GroupWise system. For example, if John Smith’s address at Novell®is
[e-mail], this address can be used by users within the GroupWise system and users
external to the system.
To set up Internet addressing, you do the following:
Define Internet domain names for your GroupWise system. You can have one or more domain
names (for example, novell.com, gw.novell.com, and support.novell.com).
Set up the default Internet address format for use when displaying user addresses in the
GroupWise Address Book and sent messages. There are six formats that can be assigned at the
system, domain, post office, or user level. In addition, there is a free-form format that can be
used at the user level.
Designate the address formats that can be used to address messages to your GroupWise users.
There are five possible formats to choose from. You can allow all five formats, or only one.
Specify the default Internet Agent to be used when sending messages from your GroupWise
system to the Internet. This becomes your system’s default Internet Agent for outbound
messages sent from all domains; however, if you have multiple Internet Agents, you can
override this setting by assigning Internet Agents at the domain level.

45.1.1 Internet Agent Requirement
Internet addressing requires you to have the GroupWise Internet Agent installed in your GroupWise
system. The Internet Agent connects your GroupWise system to the Internet. To install the Internet
Agent, see “Installing the GroupWise Internet Agent” in the GroupWise 7 Installation Guide.
45.1.2 Internet Agents Used for Outbound Messages
Each domain in your GroupWise system must be assigned an Internet Agent for outbound messages.
A domain’s assigned Internet Agent handles all outbound messages sent by the domain’s users.
If your GroupWise system includes only one Internet Agent, that Internet Agent must be assigned to
all domains and is used for all outbound messages.
If your GroupWise system includes multiple Internet Agents, you must decide which Internet Agent
you want to be responsible for outbound messages for each domain. You must select one Internet
Agent as your system’s default Internet Agent, but you can override the default at each domain.
45.1.3 Internet Domain Names
You must associate at least one Internet domain (novell.com, gw.novell.com, support.novell.com, or
so forth) with your GroupWise system. These Internet domains need to exist in the domain name
service (DNS).
After you have associated Internet domains with your GroupWise system, all users in your system
can be addressed using any of the domains (for example, [e-mail],
[e-mail], and [email protected]l.com). The addresses can be used both internally
and externally.
Preferred Internet Domain Name
You must assign each GroupWise user a preferred Internet domain. GroupWise uses the preferred
Internet domain name when constructing the e-mail address that are displayed in the GroupWise
Address Book and in the To field of sent messages.
To make this process easier, GroupWise lets you assign a preferred Internet domain to be used as the
default for your GroupWise system (for example, novell.com). The system’s preferred Internet
domain is applied to all users in your GroupWise system. However, you can override the system’s
preferred Internet domain at the domain, post office, or user level, meaning that different users
within your GroupWise system can be assigned different preferred Internet domains. For example,
users in one domain can be assigned gw.novell.com as their preferred Internet domain while users in
another domain are assigned support.novell.com.
45.1.4 Preferred Address Format
You must choose a preferred address format for your GroupWise users. GroupWise uses the
preferred address format, along with the preferred Internet domain, to construct the e-mail addresses
that are published in the GroupWise Address Book and in the To field of sent messages.
GroupWise supports the following address formats:
userID.post_office.domain@internet_domain_name

Configuring Internet Addressing 705
novdocx (en) 11 December 2007
userID.post_office@internet_domain_name
userID@internet_domain_name
firstname.lastname@internet_domain_name
lastname.firstname@internet_domain_name
firstinital lastname@internet_domain_name
As with the preferred Internet domain, you must assign a preferred address format to be used as the
default for your GroupWise system. The system’s preferred address format is applied to all users in
your GroupWise system. However, you can override the system’s preferred address format at the
domain, post office, and user/resource level.
The following sections explain some of the advantages and disadvantages of each address format:
“userID.post_office.domain@internet_domain_name” on page 705
“userID.post_office@internet_domain_name” on page 705
“userID@internet_domain_name” on page 705
“firstname.lastname@internet_domain_name” on page 706
“lastname.firstname@internet_domain_name” on page 706
“firstinitial lastname@internet_domain_name” on page 706
userID.post_office.domain@internet_domain_name
Advantages
Reliable format. GroupWise guarantees that each address is unique.
Identical usernames can be used in different post offices.
Disadvantages
Addresses tend to be long and hard to remember.
Addresses might change over time as users are moved from one post office to another.
userID.post_office@internet_domain_name
Advantages
Guarantees uniqueness if all your post offices have unique names.
Identical usernames can be placed in different post offices.
Disadvantages
Addresses tend to be long and hard to remember.
Addresses might change over time as users are moved from one post office to another.
userID@internet_domain_name
Advantages
Addresses are short and easy to remember.

706 GroupWise 7 Administration Guide
novdocx (en) 11 December 2007
Backwards-compatible with previous versions of GroupWise. (Users won’t need to update their
business cards.)
Addresses do not change as users are moved.
Disadvantages
When you first enable this address format, you might have duplicate user IDs in your
GroupWise system. However, in the future, ConsoleOne®prevents you from creating duplicate
user IDs within the same Internet domain name. The same user ID can be used in different
Internet domains without problem.
firstname.lastname@internet_domain_name
Advantages
Addresses are intuitive and easy to remember.
Addresses do not change as users are moved.
Disadvantages
When you first enable this address format, you might have duplicate first and last names in
your GroupWise system. However, in the future, ConsoleOne prevents you from creating users
with the same first and last names within the same Internet domain name. The same first name
and last name combination can be used in different Internet domains without problem.
The probability of conflicts increases if any user’s first and last names match any GroupWise
domain or post office name, if any two users have the same first and last names, or if any two
users have the opposite first and last names (such as James Dean and Dean James).
lastname.firstname@internet_domain_name
Advantages
Addresses are intuitive and easy to remember.
Addresses do not change as users are moved.
Disadvantages
When you first enable this address format, you might have duplicate first and last names in
your GroupWise system. However, in the future, ConsoleOne prevents you from creating users
with the same first and last names within the same Internet domain name. The same last name
and first name combination can be used in different Internet domains without a problem.
The probability of conflicts increases if any user’s first and last names match any GroupWise
domain or post office name, if any two users have the same first and last names, or if any two
users have the opposite first and last names (such as James Dean and Dean James).

Addresses do not change as users are moved.
Disadvantages
When you first enable this address format, you might have duplicate first initial and last names
in your GroupWise system. However, in the future, ConsoleOne prevents you from creating
users with the same first initials and last names within the same Internet domain name. The
same first initial and last name combination can be used in different Internet domains without
problem
The probability of conflicts increases when using first initials instead of complete first names.
45.1.5 Allowed Address Formats
The preferred Internet domain and preferred address format apply to user addresses as displayed in
the GroupWise Address Book or in the address displayed on sent messages.
The allowed address formats, on the other hand, determine which address formats are accepted by
the Internet Agent. There are five possible allowed formats:
userID.post_office@internet_domain_name
userID@internet_domain_name
firstname.lastname@internet_domain_name
lastname.firstname@internet_domain_name
firstinital lastname@internet_domain_name
If you select all five formats, the Internet Agent accepts messages addressed to users in any of the
formats. For example, John Peterson would receive messages sent using any of the following
addresses:
[email protected]
[e-mail]
[e-mail]
peterson.joh[email protected]m
[e-mail]
You must designate the allowed address formats to be used as the default formats for your
GroupWise system. The system’s allowed address formats are applied to all users in your
GroupWise system. However, you can override the system’s allowed address formats at the domain,
post office, and user/resource level.
For example, assume you have two John Petersons with userIDs of jpeterson and japeterson. The
userID.post_office and userID address formats do not cause message delivery problems, but the
firstname.lastname, lastname.firstname, and firstinitial lastname address formats do. To overcome
this problem, you could disallow the three problem formats for these users at the user level.
45.1.6 Override Options
In spite of the best planning, some e-mail addresses do not fit the rules and are not processed
correctly. You can handle such addresses by overriding the regular address processing, as described
in Section 45.2.3, “Overriding Internet Addressing Defaults,” on page 710.

45.2 Setting Up Internet Addressing
The following sections help you to set up Internet addressing:
Section 45.2.1, “Installing the Internet Agent,” on page 708
Section 45.2.2, “Enabling Internet Addressing,” on page 708
Section 45.2.3, “Overriding Internet Addressing Defaults,” on page 710
45.2.1 Installing the Internet Agent
Before you can set up Internet addressing, you must install the GroupWise Internet Agent. If you
have not already installed the agent, see “Installing the GroupWise Internet Agent” in the
GroupWise 7 Installation Guide.
45.2.2 Enabling Internet Addressing
1In ConsoleOne, click Tools > GroupWise System Operations > Internet Addressing.
2In the Internet Agent for Outbound SMTP/MIME Messages list, select the Internet Agent to use
as the default Internet Agent for your system.
By default, each domain uses this Internet Agent for outbound messages sent by users in the
domain. If you have multiple Internet Agents in your GroupWise system, you can override the
default setting at the domain level. For more information, see “Domain Overrides” on
page 710.
3To define an Internet domain, click Create to display the Internet Domain Name dialog box.

Configuring Internet Addressing 709
novdocx (en) 11 December 2007
4Specify the Internet domain you want to define in your GroupWise system, then click OK to
add it to the list of Internet domains.
5Repeat Step 3 and Step 4 for each Internet domain you want to define.
When you finish, all Internet domains you want to define should be listed in the Internet
Domain Names box.
The preferred Internet domain is indicated by a check mark. This is the Internet domain name
that is used when GroupWise constructs a user’s preferred e-mail address. A preferred e-mail
address is the address that is published in the GroupWise Address Book and in the To field of
sent messages. You can override the preferred Internet domain name at the domain, post office,
and user/resource levels. For more information, see Section 45.2.3, “Overriding Internet
Addressing Defaults,” on page 710.
6If the Internet domain you want to be the default preferred domain for your GroupWise system
is not already selected, select the desired Internet domain, then click Set Preferred Name.
7In the Preferred Address Format list, select your system’s default Internet address format.
This is the format that is used when displaying addresses in the GroupWise Address Book and
in a message’s From field if it is not overridden at a lower level. For a list of the available
addressing formats and their respective advantages and disadvantages, see Section 45.1.4,
“Preferred Address Format,” on page 704.
You can override the preferred address format at the domain, post office, and user/resource
levels. For more information, see Section 45.2.3, “Overriding Internet Addressing Defaults,”
on page 710.

710 GroupWise 7 Administration Guide
novdocx (en) 11 December 2007
8If desired, turn on the Enable "First Initial Last Name" Matching for Incoming Mail option.
This option allows the Internet Agent to resolve addresses for incoming messages by
performing first initial last name lookups on the username portion of the address. When doing
so, the Internet Agent uses the first letter of the username as the first initial and the remainder
of the username as the last name. It then resolves the address to any GroupWise users whose
Last Name field (in their eDirectory User object properties) contains the last name and whose
Given Name field starts with the first initial.
For example, if the recipient’s address is [email protected], the first initial would be J and
the last name would be Peterson. The address would resolve to the user whose Last Name field
is Peterson and Given Name field starts with J. If more than one user’s given name starts with J
(for example, John and Janice), the message is undeliverable.
This option is useful if you want to be able to use the UserID@Internet_domain_name format
but your userIDs do not really reflect your users’ actual names (for example, John Peterson’s
user ID is 46789 so his address is [e-mail]). In this case, you could publish users’
addresses as the first initial last name (for example, [email protected]) and enable this
option so that the Internet Agent resolves the addresses to the appropriate users.
9In the Allowed Address Formats list, select the address formats that you want to be supported
for incoming messages. GroupWise delivers a message to the recipient if any of the allowed
formats have been used in the address.
You can override the allowed address formats at the domain, post office, and user/resource
levels. For more information, see Section 45.2.3, “Overriding Internet Addressing Defaults,”
on page 710.
10 Click OK to save your changes.
If you changed the preferred address format, you are prompted to update the Internet e-mail
address (User object > General > Identification > E-Mail Address) for all affected users. The
Internet e-mail address is the address returned in response to LDAP queries to eDirectoryTM. It
is recommended that you allow this update; however, performing it for the entire GroupWise
system might take a while.
At this point, Internet addressing is enabled.
45.2.3 Overriding Internet Addressing Defaults
All domains, post offices, and users/resources in your GroupWise system inherit the defaults
(Internet Agent for outbound messages, preferred Internet domain name, preferred address format,
and allowed address formats) you established when enabling Internet addressing for your system.
However, if desired, you can override these defaults for individual domains, post offices, or users/
resources.

“Post Office Overrides” on page 711
“User/Resource Overrides” on page 712
Domain Overrides
At the domain level, you can override all Internet addressing defaults assigned to your GroupWise
system.
1In ConsoleOne, right-click a Domain object, then click Properties.

novdocx (en) 11 December 2007
2Click GroupWise > Internet Addressing.
3To override one of the options, select the Override box, then select the option you prefer for
this domain.
4Click OK to save the changes.
If you changed the preferred address format, you are prompted to update the Internet e-mail
address (User object > General > Identification > E-Mail Address) for all affected users. The
Internet e-mail address is the address returned in response to LDAP queries to eDirectory. We
recommend that you allow this update; however, performing it for an entire GroupWise domain
might take a while.
Post Office Overrides
At the post office level, you can override the preferred Internet domain name, preferred address
format, and allowed address formats the post office has inherited from its domain. You cannot
override the Internet Agent that is assigned to handle outbound messages.
1In ConsoleOne, right-click a Post Office object, then click Properties.
2Click GroupWise > Internet Addressing.

712 GroupWise 7 Administration Guide

3To override one of the options, select the Override box, then select the option you prefer for
this post office.
If you need additional information about any of the fields, click Help.
4Click OK to save the changes.
If you changed the preferred address format, you are prompted to update the Internet e-mail
address (User object > General > Identification > E-Mail Address) for all affected users. The
Internet e-mail address is the address returned in response to LDAP queries to eDirectory. We
recommend that you allow this update; however, performing it for an entire GroupWise post
office might take a while.
User/Resource Overrides
At the user and resource level, you can override the preferred Internet domain, preferred address
format, and allowed address formats that the user/resource has inherited from its post office. You
cannot override the Internet Agent that is assigned to handle outbound messages.
1In ConsoleOne, right-click a User or Resource object, then click Properties.
2Click GroupWise > Internet Addressing.

Configuring Internet Addressing 713
novdocx (en) 11 December 2007
3To override one of the options, select the Override box, then select the option you prefer for
this user or resource.
At the user and resource level, the preferred address format can be completely overridden by
explicitly defining the user portion of the address format (user@Internet domain name). The
user portion can include any RFC-compliant characters (no spaces, commas, and so forth).
For example, if you’ve selected First Name.Last Name@Internet domain name as your
system’s preferred address format and you have two John Petersons, each on a different post
office in your system, you would end up two users having the same address
([e-mail]). You could use this field to differentiate them by including their
middle initials in their address ([e-mail] and
[email protected]).
You can use the same e-mail ID for more than one user in your GroupWise system, if each user
is in a different Internet domain. Rather than requiring that each e-mail ID be unique in your
GroupWise system, each combination of e-mail ID and Internet domain must be unique. This
provides more flexibility for handling the situation where two people have the same name.
If you need additional information about any of the fields, click Help.
4Click OK to save the changes.
If you changed the preferred address format for a user, you are prompted to update the user’s
Internet e-mail address (General > Identification > E-Mail Address). The Internet e-mail
address is the address returned in response to LDAP queries to eDirectory. We recommend that
you allow this update.
45.3 Transitioning from SMTP Gateway Aliases
to Internet Addressing
For those who have been using SMTP gateway aliases to handle e-mail addresses that do not fit the
default format expected by the Internet Agent or to customize users’ Internet addresses, the Gateway
Alias Migration utility can convert the usernames in those gateway aliases into preferred e-mail IDs.
The Preferred E-Mail ID feature was first introduced in GroupWise 6.5 and is the suggested method
for overriding the current e-mail address format, as described in Section 14.7.2, “Changing a User’s

714 GroupWise 7 Administration Guide
novdocx (en) 11 December 2007
Internet Addressing Settings,” on page 236. The Gateway Alias Migration utility can also update
users’ preferred Internet domain names based on their existing gateway aliases.
Section 45.3.1, “Planning to Migrate Gateway Aliases,” on page 714
Section 45.3.2, “Preparing to Migrate Gateway Aliases,” on page 714
Section 45.3.3, “Performing the Gateway Alias Migration,” on page 714
Section 45.3.4, “Verifying the Gateway Alias Migration,” on page 716
45.3.1 Planning to Migrate Gateway Aliases
You can migrate SMTP gateway aliases by individual user, by post office, by domain, or for your
entire GroupWise system. Migrating at the post office level is recommended, although you can test
the process by migrating individual users. Assess the gateway aliases in your GroupWise system and
decide how you want to organize the migration process.
The Gateway Alias Migration utility runs most efficiently if you are connected to the domain that
owns the users whose aliases you are migrating. This reduces network traffic between domains
during the migration process.
The Gateway Alias Migration utility requires that you connect to a GroupWise 7 domain, although
you can select users from 6.xand 5.xdomains for migration. If you still have 4.xdomains, you can
migrate aliases by connecting to the GroupWise System object before connecting to a domain.
Determine the domains you need to connect to as you perform the migration.
45.3.2 Preparing to Migrate Gateway Aliases
Before starting the SMTP gateway alias migration process:
Validate each domain database (wpdomain.db) that you will connect to in order to clean up
any orphaned aliases that might exist. See Section 26.1, “Validating Domain or Post Office
Databases,” on page 377.
Create a current backup of each domain database before performing the migration. See
Section 31.1, “Backing Up a Domain,” on page 407
45.3.3 Performing the Gateway Alias Migration
To run the Gateway Alias Migration utility in ConsoleOne:
1If you want to migrate all gateway aliases in your GroupWise system, connect to the primary
domain in the GroupWise View.
or
If you want to migrate the gateway aliases in a particular domain or post office, connect to the
domain where the aliases are located.
2Browse to and select the object representing the set of gateway aliases that you want to migrate
(GroupWise system, domain, post office, or user).
3Click Tools > GroupWise Utilities > Gateway Alias Migration.
4In the SMTP Gateway Alias Type drop-down list, select the type of alias you want to migrate.

Configuring Internet Addressing 715
novdocx (en) 11 December 2007
The list of available gateway alias types is generated from the Gateway Alias Type fields on the
Identification property pages of the Internet Agent objects in your GroupWise system.
The resulting alias list provides the SMTP gateway aliases for all users associated with the
object selected in Step 2. If the list is extremely long, you can click Stop and just work with a
subset of the alias list.
The list does not include any aliases that have a pending operation on them.
5Select one or more gateway aliases to migrate.
or
Click Select All.
6Click Migrate to start the migration process.
You are prompted for how to handle each gateway alias.
If the alias is just a username, you can select whether or not you want to use that username
as the user's preferred e-mail ID.
If you do, the username is transferred into the Preferred E-Mail ID field on the Internet
Addressing property page of the User object.
If the alias also includes an Internet domain name, you can select whether or not you want
to use that Internet domain name with the user's preferred e-mail ID.

716 GroupWise 7 Administration Guide
novdocx (en) 11 December 2007
If you do, the domain name is transferred into the Internet Domain Name field on the
Internet Addressing property page of the User object.
NOTE: For an internal user, if the Internet domain name is not defined in your
GroupWise system under Tools > GroupWise System Operations > Internet Addressing,
then the Internet domain name is not transferred into the Internet Domain Name field on
the Internet Addressing property page of the User object. However, for external users,
undefined Internet domain names are transferred into the Internet Domain Name field on
the Internet Addressing property page of the External User or External Entity object.
By default, both usernames and domain names are selected for migration.
7For each gateway alias, deselect the check boxes for any actions that you do not want the Alias
Migration utility to perform, then click OK.
For convenience when migrating multiple aliases, you can click OK to All to apply your current
selections to all aliases.
8When the migration is complete, select a different gateway alias type to migrate.
or
Click Close.
45.3.4 Verifying the Gateway Alias Migration
To see what the Gateway Alias Migration utility has accomplished:
1Browse to and right-click a User object that used to have a gateway alias, then click Properties.
2Click GroupWise > Gateway Aliases.
The alias list should be empty.
3On the same User object, click GroupWise > Internet Addressing.
The Preferred EMail ID field should be filled in with the information from the old gateway
alias.

2If the SMTP/MIME Settings page is not the default page, click SMTP/MIME > Settings.
3Fill in the fields:
Enable SMTP Service: SMTP service is on by default. This setting allows SMTP Internet
messaging. This setting corresponds with the Internet Agent’s /smtp switch.
Number of SMTP Send Threads: The SMTP send threads setting lets you specify the
number of threads that process SMTP send requests. Each thread is equivalent to one
connection. The default is 8 threads. This setting corresponds with the Internet Agent’s /sd
switch.
Number of SMTP Receive Threads: The SMTP receive threads setting lets you specify the
number of threads that process SMTP receive requests. Each thread is equivalent to one
connection. The default is 16 threads. This setting corresponds with the Internet Agent’s /rd
switch.
Kill Threads on Exit or Restart: Select this option to cause the Internet Agent to stop
immediately, without allowing its send/receive threads to perform their normal shutdown
procedures. The normal termination of all send/receive threads can take several minutes,
especially if a large message is being processed. By terminating immediately, a needed restart
can occur immediately as well. This setting corresponds with the Internet Agent’s /killthreads
switch.
Enable iCal Service: Select this option if you want the Internet Agent to convert outbound
GroupWise Calendar items into MIME text/calendar iCal objects and to convert incoming
MIME text/calendar messages into GroupWise Calendar items. Enabling the iCal service
provides the functionality described in “Accepting or Declining Internet Items” in “Scheduling
Group and Posted Items” in the GroupWise 7 Windows Client User Guide. This setting
corresponds with the Internet Agent's /imip switch.

Hostname/DNS "A Record" Name: The Hostname/DNS “A Record” name setting lets you
identify the hostname of the server where the Internet Agent resides, or in other words the A
Record in your DNS table that associates a hostname with the server’s IP address (for example,
gwia.novell.com). This setting corresponds with the Internet Agent’s /hn switch.
If you leave this field blank, the Internet Agent uses the hostname obtained by querying the
hosts file from the server.
Relay Host for Outbound Messages: The Relay host setting can be used if you want to use
one or more relay hosts to route all outbound Internet e-mail. Specify the IP address or DNS
hostname of the relay hosts. Use a space between relay hosts in a list. Relay hosts can be part of
your network or can reside at the Internet service provider’s site. This setting corresponds with
the Internet Agent’s /mh switch.
If you want to use a relay host, but you want some outbound messages sent directly to the
destination host rather than to the relay host, you can use a route configuration file
(route.cfg). Whenever a message is addressed to a user at a host that is included in the
route.cfg file, the Internet Agent sends the message directly to the host rather than to the
relay host. For information about creating a route.cfg file, see Section 46.1.9, “Using a
Route Configuration File,” on page 732.
Scan Cycle for Send Directory: The Scan cycle setting specifies how often the Internet Agent
polls for outgoing messages. The default is 10 seconds. This setting corresponds with the
Internet Agent’s /p switch.
Use 7 Bit Encoding for All Outbound Messages: By default, the Internet Agent uses 8-bit
MIME encoding for any outbound messages that are HTML-formatted or that contain 8-bit
characters. If, after connecting with the receiving SMTP host, the Internet Agent discovers that
the receiving SMTP host cannot handle 8-bit MIME encoded messages, the Internet Agent
converts the messages to 7-bit encoding.
With this option selected, the Internet Agent automatically uses 7-bit encoding and does not
attempt to use 8-bit MIME encoding. You should use this option if you are using a relay host
that does not support 8-bit MIME encoding. This setting corresponds with the Internet Agent’s
/force7bitout switch.
Maximum Number of Hours to Retry a Deferred Message: Specify the number of hours
after which the Internet Agent stops trying to send deferred messages. The default is 96 hours,
or four days. A deferred message is any message that can’t be sent because of a temporary
problem (host down, MX record not found, and so forth). This setting corresponds with the
Internet Agent’s /maxdeferhours switch.
Intervals to Retry a Deferred Message: Specify in a comma-delimited list the number of
minutes after which the Internet Agent retries sending deferred messages. The default is 20, 20,
20, 240. The Internet Agent interprets this list as follows: It retries 20 minutes after the initial
send, 20 minutes after the first retry, 20 minutes after the second retry, and 240 minutes (4
hours) after the third retry. Thereafter, it retries every 240 minutes until the number of hours
specified in the Maximum Number of Hours to Retry a Deferred Message field is reached. You
can provide additional retry intervals as needed. It is the last retry interval that repeats until the
maximum number of hours is reached. This setting corresponds with the Internet Agent’s /
msgdeferinterval switch.
Do Not Publish GroupWise Information on an Initial SMTP Connection: Select this
option to suppress the GroupWise version and copyright date information that the Internet
Agent typically responds with when contacted by another SMTP host or a telnet session. This
setting corresponds with the Internet Agent’s /nosmtpversion switch.

46.1.2 Using Extended SMTP (ESMTP) Options
The Internet Agent supports several Extended SMTP (ESMTP) settings. These are settings that
might or might not be supported by another SMTP system.
The following ESMTP extensions are supported:
SIZE: For more information, see RFC 1870 (http://www.ietf.org/rfc/rfc1870.txt).
AUTH: For more information, see RFC 2554 (http://www.ietf.org/rfc/rfc2554.txt).
DSN: For more information, see RFC 3464 (http://www.ietf.org/rfc/rfc3464.txt) and RFC 3461
(http://www.ietf.org/rfc/rfc3461.txt).
8BITMIME: For more information, see RFC 1652 (http://www.ietf.org/rfc/rfc1652.txt).
STARTTLS: For more information, see RFC 3207 (http://www.ietf.org/rfc/rfc3207.txt).
To configure ESMTP settings:
1In ConsoleOne, right-click the Internet Agent object, then click Properties.
2Click SMTP/MIME > ESMTP Settings.
3Fill in the fields:
Enable Delivery Status Notification: Turn on this option to allow the Internet Agent to
request status notifications for outgoing messages and to supply status notifications for
incoming messages. This requires the external e-mail system to also support Delivery Status
Notification. Currently, notification consists of two delivery statuses: successful or
unsuccessful.
If you enable the Delivery Status Notification option, you need to select the number of days that
you want the Internet Agent to retain information about the external sender so that status
updates can be delivered to him or her. For example, the default hold age causes the sender
information to be retained for 4 days. If the Internet Agent does not receive delivery status
notification from the GroupWise recipient’s Post Office Agent (POA) within that time period, it
deletes the sender information and the sender does not receive any delivery status notification.
