Enabling mass mailer cleanup
You can configure Symantec Mail Security for SMTP to delete mass-mailer,
worm-infected messages. These types of messages are spread by mailing
themselves to names and addresses in users’ address books. This feature causes
all email messages that are detected as mass mailer worms to be dropped.
When the mass mailer cleanup function is enabled in the administrative
interface, Symantec Mail Security for SMTP searches for a match between virus
name patterns and the signatures that are returned by the antivirus scan. The
match is made based on the configuration parameter @m (used by Symantec
Security Response to name mass mailer viruses). If a match is detected, then the
message is dropped.
Even when the mass mailer cleanup function is disabled, messages that have
detectable viruses in the outer MIME container (that is, the message itself, not
the attachments within it) will be dropped. This is because Symantec Mail
Security for SMTP believes that the message is infected in a way that is not
repairable and not deletable.
To enable mass mailer cleanup
1
On the Symantec Mail Security for SMTP administrative interface, in the
left pane, click
Antivirus Policy
.
2
In the Antivirus Settings window, under Mass Mailer cleanup, select
Enable
Mass Mailer cleanup
.
This option is enabled by default.
