Topic: Filter by text in body or subject
I want to create a manual filter based on a string on subject or body of message. Can you point me where to start?
For a specific reason, I dont want some of my users receive messages with "Undelivered Mail Returned to Sender" on subject.
Let me know where to look. I dont know if it's a SpamAssassin local.cf, or Amavis or other place...
