I guess I was moving too quickly earlier this week when I ruled POPFile out as a solution for Entourage Spam Filtering thinking that it could only support Subject modification and not extra headers… Seems in fact that it can do the X-Text-Classification: method which is great since my accuracy scoring with POPFile is excellent – 97+%. I have SpamSieve set to run in my rules right after POPFile searches for Spam which lets me catch any loose ends. All this stuff drops into my Spam folder for checking and deletion.
POPFile is a much stronger solution to SpamSieve though together they seem like a solid bullet-proof vest for spam.
Since POPFile requires a bit more technical oomph to get going, I thought it would be once again worth while to link to Michael Artz’ excellent instructions for installation on Mac OS X.
