[Mimedefang] Getting MIMEDefang to ignore .zip files andcontents

[Paul Rawlings]

Thank you all for the responses - it was something nice and simple.

I can imagine many of you frowning upon turning off this feature and it
was a tough call to make.
All of our Windows boxes do run SAV and are attached to a local SAV
server so they are running the latest definitions.
Laptop users who have been away from our network are definition updated
before they can get into e-mail etc.

Thanks again.

Paul

I think this is a bad bad idea.  You never know what could be sent
inside zip files.  

The code your probably looking for to comment out:



    # Look inside ZIP files
    if (re_match($entity, '\.zip$') and
        $Features{"Archive::Zip"}) {
        my $bh = $entity->bodyhandle();
        if (defined($bh)) {
            my $path = $bh->path();
            if (defined($path)) {
                return re_match_in_zip_directory($path,
$re);                               }
        }
    }   

This ONLY reflects whats in the standard filter supplied with the
software.  If your admin changed it, it could be signifigantly
different.

Hope you have some mandatory way of scanning these when your users
recieve them on their desktops.
