Symantec is updating its Mail Security for SMTP product,
offering new features for cleaning up after mass-mailing worms and
identifying trusted mail domains, as well as improved capabilities
for detecting spam.
Mail Security for SMTP 4.0 combines antivirus, e-mail content
filtering and spam prevention. It scans e-mail at the SMTP (Simple
Mail Transfer Protocol) gateway before it reaches an organisation's
mail server or user inboxes.
A new feature in Version 4.0 automatically collects and monitors
so-called "trusted" internet domains from which e-mail messages
should be accepted without having to pass through the product's
heuristic spam filters and "blacklists" of banned domains. The
feature will reduce false positives, in which legitimate e-mail
correspondence is flagged as spam.
A Mass Mailer Cleanup feature helps companies eliminate the
flood of e-mail traffic generated by mass-mailing worms such as
Netsky and Mydoom. Many gateway antivirus products strip out
virus-tinged e-mail file attachments or quarantine the e-mail
message. However, Mail Security for SMTP 4.0 deletes the entire
message and its attachment, reducing the amount of virus-generated
e-mail that ends up on mail systems.
Other new features include the ability to customise spam
filtering rules that look for specific text or keywords, as well as
undesirable or offensive language and message content. Customers
will also now be able to insert custom text, including legal
disclaimers, to outgoing mail messages.
Pricing starts at $15 per user for licences of 10 to 25 users.
For a 2,000-user licence, the cost is around $10 per user.
