Yes they do. But they can also be misused, by for instance the zip file you
provided the link for. My servers did'nt take harm of this file, but I'm
sure that if I did'nt have the free disk space I have on my servers, they
would.
I'm not sure what qmail-scanner does if the process running out of disk
space. If it removes the uncompressed files, or if it leaves it there. I'll
better test that ;-)
Of course the server would have problems when several instances would
connect sending this file, and this will happen with qmail-scanner since
qmail-scanner-queue.pl don't terminate the smtp session until the mail is
finnished scanned. This would make the other server timeout, resending the
mail.
Then again, qmail-scanner/perlscan_scanner provides the ability to deny the
mail based on the attachement being of type .zip and of size 42374 bytes
solving that problem.
I guess both of us can agree on the fact that there is a lot of different
ways to make malicious damage to mailservers.
