    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...
