I have set up my Domain Level Content Filtering and I'm catching all the spam and putting into their own folders, like Bad Domain, Bad E-mail Address etc. Each Filter that I have configured has a subject prefix so that I know what filter caught it. HOWEVER, I'm getting a lot of spam that is NOT prefixing to the subject so I don't know what is catching it.
Note too that I have configured the Antispam at the ADMINISTRATION level to also prefix the subject for levels 10, 20 and 30. BTW, I have also set the Domain in question to "Override spam settings for this domain".
I have searched high and low on the knowledge based but I can't find anything that explains what has priority over the other or in what order the spam filtered are fired.
Can some point me in the right direction to find the answer or let me know what I'm doing wrong.
