Thx! I do use Maildir, so I may try this out and see how well SpamAssassin does with better training. I've also tried dspam out recently, and it seemed to be quite good as well. One thing I really like about SpamSieve now that I've been using it for a couple weeks is the corpus browser. Really handy to drill down to some words and see how they're categorized. The instant stats screen is nice too. The big problem with a spam filter that runs on the client, however, is that you always need to leave the client running. Well, it's a problem if you're like me and check your email from a variety of computers, anyways.

When a message is miscategorized simply move it to the appropriate folder and make sure it's marked as seen: find ~/Maildir -type d -maxdepth 1 -mindepth 1 ! -iname .Trash ! -iname .Spam ! -iname .unblocked-spam ! -iname .junk -exec find {} -type f -mtime -3 -name \*S \; | sa-learn --ham -f - find ~/Maildir/.Spam/cur/ -name \*S | sa-learn --spam -f - Note that this approach assumes you use a Maildir-based IMAP server; for a pure IMAP approach I've actually used the Perl Mail::Box module to make an IMAPS connection and loop over the appropriate mailboxes - the only drawback to that approach is that it requires you to either run it interactively or store your mail password in a file (yech).
