Hi,
In our constant quest to block outgoing spam, we are testing to block emails by specific words in the subject line using the system_filter.exim file. For example we have the following rule:
With this rule all emails containg the word "money" in the subject line will be blocked.
Does anyone know how to edit this rule so it affects only outoing messages?
Any other suggestions on how to block outgoing spam from our servers when an email account gets compromised?
Thanks in advance for your time guys!
