clamAV for virus spamprobe for spam
I highly recommend both of them. Spamprobe is just fantastic. However they both suffer from the fact that they require per-user integration (typically via procmail). Thats great for a 10 user box, its unworkable for a 10,000 user box. My box is a 10 user box so I love them. I know there are site-wide integrations for both of them but I've not tried them ... and with spamprobe its largely against its design ... so I'm not confident of a global spam bayesian database ... you know "my spam" != "your spam" ... I could use a good home refinance and cheep drugs :) Thats why I love spamprobe, I own my spam definitions. Mine all mine !!!!
I am looking at this "assp" ... I like the idea of a configurable smtp layer filter, although I detest RBL's ... being configurable is nice (I can turn OFF the RBL). I dont like that its in perl due to my admited huge bias, but if it really works well I could maybe overlook that ... I try to be language agnostic in theory ... but sometimes I have a hard time ... being that I've written software in most languages, enough to grow a few biased oppinions :)
