Using Anti-Spam and Anti-Phishing
Spam is unsolicited e-mail, often of a commercial nature, sent indiscriminately to
multiple mailing lists, individuals, or newsgroups. Phishing are Internet scams
designed to trick the recipients into revealing credit card, passwords, Social Security
numbers, and other personal information to individuals who intend to use them for
fraudulent purposes.
Yoggie Gatekeeper™ provides protection against Spam and Phishing by integrating
the powerful MailShell™ engine. Every e-mail, whether incoming or outgoing, is
scanned by Yoggie Gatekeeper™ to identify and neutralize any security threats in the
same manner that all network data is scanned. This includes viruses, spyware, active
content, etc. The dedicated e-mail security scanners incorporate four different
engines, SpamBulk,SpamRepute,SpamContent and SpamTricks.The engines generate a
score, from 0 to 100, using specialized Bayesian algorithms. In addition, Yoggie
Gatekeeper generates a category-based score which is inserted into the subject line:
[Spam]
[Probably Spam]
[Phishing]
Yoggie Gatekeeper also generates two spam header files, which can be found in the
message source and will include the following information:
X-Yoggie-SpamScore – the exact spam score, 0-100. 100 is definitely spam, 0
is definitely not spam.
X-Yoggie-SpamLevel – Indicates Spam, Probably Spam, Phishing, or empty if
not spam.
In the user's e-mail program, rules can be created to handle these tagged. You can,
for example, the e-mail program can automatically delete all e-mails tagged by
Yoggie™ as spam.
