I'm not sure how handy you are with C (I think there are perl bindings as well), but if you (or one of the other sysadmins) is marginally proficient, the milter API is very straightforward and makes it very easy to do tasks like this. In this particular example you would just be scanning for the email header with the SA score and then silently dropping the email if its spam score is too high. There's probably an already made solution out there for you in this particular case, but if you want to do anything interesting with your mail setup learning how to write Milters is a good way to go. -- Evan Klitzke -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
