[Mimedefang] Using more than one virus scanner is a good idea.

Guys

We came across a problem using virus scanners on .zip files with the 
--unzip etc on clamav. One of our users decided to send a 127MB 
attachment zipped to 5MB. To cut a long story short, the mail server 
timed out/ran out of disk space.

We overcame the problem with a file size limit on virus scanning, copied 
from the limit for spamassassin calls.

    if (-s "./INPUTMSG" < 100*1024) {
...

Maybe this should be part of the standard filter. Any thoughts?
