Well, then if you're on a persistent connection (broadband, DSL, etc.), why not just run your own as Ted suggested? That's what I did, mostly because I wanted more control over how I used my email. And for the learning experience - which was more valuable to me personally. Funny thing is that I still get 90% of my spam thru my MediaOne account - even given that I am on 6 different mailing lists (down from 10) and I use addresses from 4 different domains. They certainly aren't filtering. I tried some of the bundled procmail filters out there, but they are pretty much geared toward local mbox type stuff. They can usually be modified to work with my imap server, but often they wind up having an unacceptable level of false positives. The spambnc port regarded all freebsd listmail as spam. I could have whitelisted anything from freebsd-questions, but then the spam that gets thru the freebsd filters (?) would always get thru. I've settled for filtering on key phrases and black and white lists. It helps. I trash any blacklisted recips, and dump phrase hits into a spam folder. It is a good bit of up front work, and as one poster in this thread mentioned, it requires regular maintennance, but I've started reducing the time I have to put into it now. I just remembered that I wasn't going to post on this again, but since I've gone thru the trouble of writing all this out, I'll bless you all with my babbling on the subject just once more. :) I do realize Mike, that you may not have (or desire or need) such connectivity, but there are surely ways you can get mail at an account that doesn't filter? I know there are ways to complain about spam, but I haven't yet gotten around to automating the blacklist bounces and complaints. Maybe next month.
