You need to implement an AVirus tool like ClamAV and integrate it with your spamssassin and qmailqueue/scanner efforts. My scanner kills of virii (ClamAV is catching the message.zip virus these days) instead of delivering. You're only half way there....

view the setup for these bits here:

thx, but I cant just filter those e-mail by qmail itself? like setting some control file in control/ and block specific file, let say, I dont want *.exe exist in our mail.

then which AVirus is good? and has auto updated in denfinition?

I think it a little narrow minded to target specific extensions when there are anti-virus products (such as ClamAV) that are autoupdated with anti-virus signatures to address such baddies in any form.

You can contemplate your options from the list here:

Otherwise, setting up an autoupdating AV solution as I previously linked will do a great deal of good for all your users.

Good luck.
