Re: [gentoo-user] Virus protection for Evolution users
This will only check incoming messages, and I have not tested this setup personally. Download and install clamav and set up automatic signature updating. Create a folder 'virus' or something in evolution, now set up a filter like is adviced for spamassasin at http://www.atlantawebhost.com/articles/evolution_spamassassin.php Replace the spamassasin command with clamscan --mbox. Now if a virus is found, Evolution will move the message to the virus folder... you can run clamscan again on the mbox file in the evolution subdirectory to identify the virus.

Hi, This was exactly the scenario. This new worm can be embedded in a zip file. Simple Postfix attachment filters don't reject it. I'm typing this on a Windows/Outlook machine with Norton Antivirus that has received something like 15 of these attachments just this morning. Norton catches them so no big deal. However, on my Linux box maybe I don't open the zip file, but for one reason or another, today or some day in the future, I forward the email to someone else. They get infected since they run Windows. Granted, it's their fault they got infected at all, but I can do the world a little favor by not forwarding this things, right? I see another email just arrived saying clamav. Thanks to Peter for that. There's also one called Kaminski or something like that for Linux, but that's for money. Anyway, thanks for the ideas.

Also several mta's have the ability to do attachment filtering, one mta-proxy I like is messagewall, it can easly do virus scanning with clamav or f-prot, dns blacklist lookups, and other spam prevention type handleing before your favorite mta even sees the message. -- [EMAIL PROTECTED] mailing list
