NVM-DFx - SMTP Email Integration 1
Introduction
The NVM-DFx Voice Mail system can be integrated with an SMTP Email Server and
can be configured to operate in a POP3 or IMAP4 environment.
Figure 1-1: Typical Voice Mail/Email Integration
SMTP integration allows Voice Mail to send Voice and Fax messages to any POP3
or IMAP4 Email client. An incoming Voice Mail or Fax message appears on the
SMTP client in the same list as incoming Emails. Email users can read, delete, reply
to, and forward Voice and Fax messages that are in their POP3 or IMAP4 account.
Any of the following Email applications can be used as an SMTP client to view
messages:
■MS Outlook
■Outlook Express
■Web based - See service provider
When a Voice/Fax message is sent to the POP3 account, and the user deletes or
reads the message, it will not be deleted or marked as read in the Voice Mail
mailbox. However, if the Voice/Fax message is deleted from the Voice Mail mailbox,
an attempt is made to delete it from the POP3 account, provided the user mailbox
has POP3 information programmed. If the POP3 mailbox information is left blank,
no attempt is made.

Compatible
Features
Once the Voice Mail unit is integrated with an SMTP Email server, the following
features and options can be used:
Unified Messaging is the feature that allows Voice, Fax, and Email to be received
on the same client PC, using Outlook or other Email application. Each Voice Mail
Server is shipped with a default number of Unified Messaging seats. This number
can be expanded by purchasing additional seats. All that is required for the default
number of Unified Messaging seats to be active, is to perform the SMTP integration.
Text-to-Speech copies your Email text messages and converts them to synthesized
speech so that you can listen to them through your Subscriber Mailbox at a
telephone. A digital voice synthesizer tells you the sender and subject before
reading you the actual Email message.
Synchronization is a feature of IMAP4 that allows the actions performed at a
subscriber mailbox to be repeated at the Email server and vice versa. For instance,
if synchronization is enabled and a subscriber deletes a message in his mailbox,
the message will also be deleted on the server.
Unified Messaging Mailbox Options is a software component that can be installed
on the Email client, so that SMTP accounts can be created locally by the client,
rather than at the Voice Mail Server.
Comparison
of Integration
Types
The table below offers a comparison of the features available for each type of
server:
Requirements ■The Voice Mail server must be connected to a network that has access to
the Email server, and the Network Configuration must be set to the correct
TCP/IP addresses.
■The SMTP Integration software must be installed on the Voice Mail server. If
this feature was ordered with the NVM-DFx, the software will already be
installed.

Changing the SMTP Configuration
Normally, the default configuration of the NVM-DFx is for Imap4. If your Email
server does not support this, and you need to use the Text-To Speech option, you
can change the SMTP configuration.
To change the SMTP configuration from Imap4 to Pop3:
1) Select Misc Setup from the Tools section of the main menu:
2) Locate the option g_szEmailDllPath and click on the digit in the Ignore column.
This will display a dialog box which will allow you to edit the value for this option:
3) In the Value field, replace "imap4" with "pop3" by writing over.
4) Make sure that the Ignore digit is set to "0".
5) Click the Apply changes button. The new value for the Email option should now
be displayed as "/usr/local/vm/lib/libsmtppop3.so"

SMTP - Simple Mail Transport Protocol
8 NVM-DFx - SMTP Email Integration
SMTP - Simple Mail Transport Protocol
SMTP (Simple Mail Transfer Protocol) is a TCP/IP protocol used in sending Email.
SMTP uses a
spooled or queued method of mail delivery. Once a message has
been sent to a destination, the message is spooled to a device, usually a disk.
However, since it is limited in its ability to queue messages at the receiving end, it is
usually used with one of two other protocols, POP3 or IMAP, that lets the user save
messages in a server mailbox and download them periodically from the server.
Typically, a program that uses SMTP sends messages from a mail client to a mail
server and a program using either POP3 or IMAP retrieves messages from the
server to an Email client. Microsoft Exchange includes an SMTP server and can
also be set up to include POP3 support.
POP3 (Post Office Protocol 3) is the most recent version of a standard protocol for
receiving Email. POP3 is a client/server protocol in which Email is received and
held in a single mailbox on the server. Periodically, the client Email receiver checks
the mailbox on the server and downloads any mail. POP3 can be thought of as a
"store-and-forward" service. POP3 is designed to delete mail on the server as soon
as the user has downloaded it. However, some implementations allow users or an
administrator to specify that mail be saved for some period of time. The POP3
protocol is built into most popular Email products, such as Eudora and Outlook
Express. It's also built into the Netscape and Microsoft Internet Explorer browsers.
The IMAP (Internet Message Access Protocol) is an alternative protocol for
accessing Email from your local server. IMAP represents an improvement over POP
by allowing a client to access and manipulate Email messages on a server such as
retaining messages and organizing them in folders. IMAP4 is a client/server
protocol in which Email is received and held by the server. IMAP can be thought of
as a “remote file server”. The Email client can view just the heading and the sender
of the letter and then decide whether to download the mail. You can also create and
manipulate multiple folders or mailboxes on the server, delete messages, or search
for certain parts or an entire note. IMAP requires continual access to the server
during the time that you are working with your mail.

NVM-DFx - SMTP Email Integration 9
SMTP
Sequence
SMTP commands are ASCII strings terminated by a CRLF combination. Here is how
a typical SMTP connection works:
The client has responsibility for delivering a message to one or more envelope
recipients, or notifying an envelope sender if delivery is not made. It wants to
transfer this responsibility to the server.
The client waits for the server's greeting:
220 heaven.af.mil ESMTP
If the server does not accept the connection, the client quits.
The client then sends a HELO request, and waits for the response:
HELO sun.af.mil
250 heaven.af.mil
If the server does not accept the request, the client quits.
The client then sends a MAIL request showing the envelope sender address, and
waits for the response:
MAIL FROM:<[e-mail]>
250 ok
If the server does not accept the request, the client quits.
The client then sends one RCPT request for each envelope recipient address,
waiting for a response after each address:
RCPT TO:<[e-mail]>
250 ok
It keeps track of which addresses are accepted. If none of the addresses are
accepted, the client quits.
The client then sends a DATA request, and waits for the response:
DATA
354 go ahead
If the server does not accept the request, the client quits.
The client then sends the encoded message, waits for the response, and quits:
Date: 8 Aug 1998 04:10:45 -0000
From: [e-mail]
To: [e-mail]
Subject: chariot is back in service
I patched up the wheel. It's as good as new.
250 ok 902549473 qp 24035
.
QUIT
221 heaven.af.mil
If the client encounters a message I/O error, it closes the connection immediately,
without sending a final dot and without sending a QUIT request.

For each recipient, the client decides whether responsibility was transferred to the
server. There are three possible results:
Success: The server accepted responsibility for this recipient. The client is no
longer responsible.
Deferral: The server temporarily rejected responsibility for this recipient. The
client will try again later.
Failure: The server permanently rejected responsibility for this recipient. The
client will notify the sender.
This result is determined by the first digit of the server's response codes for the
connection (C), the HELO request (H), the MAIL request (M), the RCPT request for
this recipient (R), the DATA request (D), and the encoded message (E), according
to the following table:
C H M R D E Result
5 deferral (some clients: failure)
4 deferral
2 5 deferral (some clients: failure)
2 4 deferral
2 2 5 failure (a few clients: deferral)
2 2 4 deferral
2 2 2 5 failure
2 2 2 4 deferral
2 2 2 2 5 failure
2 2 2 2 4 deferral
2 2 2 2 3 5 failure
2 2 2 2 3 4 deferral
2 2 2 2 3 2 success
