Why are Spam messages that contain attachments triggering SpamCensor but not being blocked?

This article applies to:

• Trustwave MailMarshal (SEG)

Question:

• Why are Spam messages that contain attachments triggering SpamCensor but not being blocked?

Cause:

In MailMarshal installations that were originally installed on much older versions, default message size conditions are included in the default SpamCensor rules. The rules do not trigger for messages over a certain size. 

Resolution:

Any rules in the MailMarshal configuration that are configured to only trigger for spam messages that are below a size should have the size condition removed.
