After those recent freaking virii around , I'm trying to find a way to block them...
What's the best way to do this?
I want to avoid sending unnecessary bounces (specially because I'm the postmaster for a domain that has about 1300 users and lots of virii bounces dailly , which are almost driving me mad, so I want to avoid unnecessary pain to other domain admins) ...
Should I just reject messages containing the damned extensions (scr,com,pif,bat) or should I accept them , scan them using some antivirus and then drop the bounces of infected messages? The second option leaves the risk of someone sending a valid pif or bat file that has "format c: /X /Q" , "deltree c: /y" or something like that , but leaves the valid e-mails coming... (even though I believe that normal windoze users dont send this kind of attachment)...


Right now my server is a standard redhat 9 at work and a FC1 at home , both using sendmail... How can I do this?
(hints for qmail and postfix are welcome also , as we're thinking about switching from sendmail to qmail or postfix)


Thanx...

You should take a look out ther at a program called - AmavisD-New it's supports a ton of different virus scanners, content filtering, and has hooks to plugin Spam Assasin. basically installing a virus scanner for Linux is just one step you need a program to hook it into sendmail, and AmavisD does this well IMHO.
