[avast! - SUSPICIOUS] message in SMTP [Solved]

Is there anyway of preventing or changing the appearance of the statement "[avast! - SUSPICIOUS] " when an email is sent / recieved without a subject heading?

I only ask because some of our “users” (that’s a dirty word here) are getting panicky about it.

Hi, you can disable this feature by unchecking “Subject structure check” in Customize dialog for heuristic. Hope this helps…

Great thanks!
