At work I'm forced to use gmail. As I don't like its interface (including the strange imap semantics) I just pull everything via pop3 to my own server. At "home" I just use postifx/dovecot-imap. I use spamassassin as the spam filter. With most lists I filter in my fetchmailrc before calling to spamassassin, as those lists rarely have spam. Debian lists seem to have more spam than others[1] and thus I do filter them. Even with spamc (the small client that connects to a running spamassassin daemon) I can still get heavy load from several simultanious assassinations. Hence I have: # The lock file ensures that only 1 spamassassin invocation happens # at 1 time, to keep the load down. # :0fw * < 256000 | /usr/bin/spamc To make it simpler to search for mistakes, I filter the worst offenders to a separate folder: :0 * ^X-Spam-Level: \*\*\*\*\*\*\*\*\*\*\*\*\*\*\* .spam-bad/ :0 * ^X-Spam-Status: Yes .spam-maybe/ I use the 'autolearn' feature of SA (which is enabled by default). This saves me most retraining, but I still need to correct errors. If a spam does get through I move it to the folder 'spam' . In my crontab I have a daily job that learns new spam from there. $ crontab -l # m h dom mon dow command 10 4 * * * /home/tzafrir/bin/spam_learn $ cat /home/tzafrir/bin/spam_learn #!/bin/sh DIR=$HOME/Maildir/.spam DIR_NEW=$DIR/new DIR_CUR=$DIR/cur sa-learn --spam $DIR_NEW $DIR_CUR [1] This is due to the policy of allowing anyone to post. I must say that I'm surprised at just how little spam gets through - Admins of the liszt-server are doing a great job. And I fully appreciate this policy and occasionally post to Debian lists I'm not subscribed to) -- Tzafrir Cohen | tzaf...@jabber.org | VIM is http://tzafrir.org.il | | a Mutt's tzaf...@cohens.org.il | | best ICQ# 16849754 | | friend -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
