In fact checking GPG signatures when fetchmail downloads mails will kill my machine. Right now after night I have to download about 200 mails. Bayesian filtering + procmail takes my machine about 10-15 minutes to sort out this. With GPG signatures I will have to get up one hour earlier ;) > > Filtering every such mail isn't a solution for me. > How come?

Sure I can write very complicated rules for procmail + bogofilter + spamassasin + gnupg checks + <put whatever you want>, but hey... every check needs CPU power and harddrive access. > There is a tool that does a very good job for keeping spam > away from your box if you're willing to put some effort in configuring it > (I'm not using it personally, but my boss is - with a great success) - > http://www.tmda.net/ That looks interesting.

Mail mentioned by me was the *first* GPG signed spam I ever seen ;) regards fEnIo -- _ Bartosz Fenski | mailto:fenio@o2.pl | pgp:0x13fefc40 | IRC:fEnIo _|_|_ 32-050 Skawina - Glowackiego 3/15 - w. malopolskie - Polska (0 0) phone:+48602383548 | Slackware - the weakest link ooO--(_)--Ooo http://skawina.eu.org | JID:fenio@jabber.org | RLU:172001
