delete spam on server

[fourhead]

i'm currently using thunderbird as my pop3 email client for multiple accounts from me & my girlfriend. especially my girlfriends gets A LOT of spam every day, so i'm using the thunderbird junk mail filter, which works almost perfectly. the only disadvantage is that it fist downloads the e-mail and then removes it. so my question: is there any thunderbird-like anti-spam utility that can delete junk _before_ it is downloaded? i had a look at mailfilter, but i guess i had to update it's filters all the time. any ideas or suggestions?

thanks,
tom

Are you sure that you are willing to trust a spam filter enough to delete mail automatically?

You might like to try putting SpamAssassin on the server and using procmail as the local delivery agent. Anything marked as spam by the assassin can be shuffled to a secondary location (spam folder) or deliver to /dev/null.

you might want to try disspam, from the freshmeat page:

"DisSpam is a personal solution to combat unwanted email (i.e. not for mail servers/ISPs). It is a Perl script that accesses POP3 mailboxes and can block/forward mail based on SpamAssassin, built-in blacklist (RBL) checks, or configurable expression matches. It can be run through a variety of ways, including cron, and uses a very simple yet versatile configuration file."

i run it as a cronjob every 10 minutes, saving the mails detected as spam to a local mbox (so that i can open it in pine, skim through it fast for false-positives and delete the rest) and it saves a lot of time deleting the spam manually.

disspam is available through emerge.

hope it helps!

You want MailScanner my friend. Use this with spamassassin and you can delete all spam mails over a certain score. We currently delete all email with a score over 10. Not to mention you can add a virus scanner like sophos to it and boom you scan incoming and outgoing mail. MailScanner rocks! These are just a few of the awesome features it has.

There are many ways to do this...on my current system, I do the following (note that this is not by any means the best way...but it works):

fetchmail gets the mail from the ISPs POP3 server and delivers it to postfix, which in turn sends it to procmail. The user's .procmailrc file sends it through SpamAssassin, which processes it and sends it back. If it's marked as spam with a high enough score it gets moved into a separate holding area for later review. Lower scored spam is delivered and handled by the mail client.

I'm not suggesting you set things up this way, I just wanted to give you some more ideas.
