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.
