"Can I use the SMTP_SERVER_REJECT file to reject mail based on the subject?"
Question:
Can I reject something based on its subject? For example: anything that has ILOVEYOU in the subject?
Answer:
Yes, by using the ":rfc822:" reject rules. For exmaple: the following lines would reject all messages that have "ILOVEYOU" in the subject space:
!
! Reject anything with an RFC822 Subject header of ILOVEYOU
! cyberpromo.com or nowhere.com
!
:Subject: ILOVEYOU
