After upgrading qmailtoaster I found out that badmimetypes was
blocking all .exe and certain .zip attachments without a warning in
the smtp log or to the sender. So I removed usage of badmimetypes from
my toaster as I have attachment filtering defined in simcontrol file
too.
My question is:
Why is attachment filtering done with two different filters:
badmimetypes and simscan?
Is it because with badmimetypes you can filter specific files
(viruses)? If so, why is badmimetypes blocking also all .exes,
shouldn't that be left to simcontrol? What should my badmimetypes
control file look like if I want to block only certain common viruses
and use simcontrol to filter away .exes and so on? Or am I missing
something here?
The badmimetypes and badloadertypes came from the warlord package that
has been part of the package for a while now. The new version of QMT has
a modified version of simcontrol, which also offers some of the same
features as warlord. Since warlord offers some features not included
with simscan, it has been left it the package. It is better at catching
known virus signatures (since it looks at the actual MIME encoding).
Since it was a new addition (simscan), the functionality of the two
where they overlap has not been modified as of yet.
