Hi, We have a Plesk server running 7.5.2. Spam Assassin is configured server-wide to flag anything with a score of 5 or above as spam, and modify the subject to say ****SPAM CAUGHT BY ourdomain.COM**** While it does seem to be catching spam, it's not modifying the subject of the emails. If we open the email, it will have the standard Spam detection software, running on the system "blah.domain.com", has identified this incoming email as possible spam. message, but the subject is left untouched. I can't seem to find any rhyme or reason for this. Does anybody have any ideas? Thanks.
