100 Kaspersky Anti-Spam 3.0
Data: Message Size
Operation: less than
Parameter: 500000
Action: external filter
Parameters: kas-cgpro
Specific features of using kas-cgpro with Communigate Pro:
• During an SMTP session, the kas-cgpro client module cannot reject an
incoming message for which the reject this message action is specified.
Instead, Communigate Pro sends a bounce message to the sender that
the message cannot be delivered to the recipient.
• The bounce message text is defined by the mail server rather than the
value of the Bounce message parameter specified by the web interface
of the Management Center (see section 4.5.4 on page 60).
• The filtering server sends messages from the monitoring system and error
messages using the mailflt3 user account. Since Communigate Pro by
default does not add to its database the accounts of system users, you
will have to create manually a mailflt3 user account in the user database
of Communigate Pro.
• When the Drop Root option is used in Communigate Pro, the mail server
is switched to using the privileges of user nobody. The switch does not
affect the kas-cgpro module resulting in a loss of connection between the
mail server and its client module. Perform the following steps to restore
their connection:
o Use the Settings→General→Helpers menu of Communigate
Pro to disable the use of the kas-cgpro filter unchecking the
Use Filter box. Click the Update button to update the
configuration.
o Add the kas-cgpro filter again. Filter parameters are listed
above in the description of Communigate Pro configuration for
work with the kas-cgpro client module.
