I have an old machine with qmail on it. Clamdscan took a
very long time
to scan files and I wanted to change the av scanner. I went
for
bitdefender console. Indeed at a 14MB archive the time was
tripled when
using clam.
Now... When qmail receives a mail it sends it to qmail
scanner that
parses it and breaks it into a few files in a temporary
directory.
When I send an email containing a virus archived with rar it
passes the
scanner. Clam worked just fine. Now, for the kicky part:
I tinkered with the qmail-scanner script and changed it to
show in
detail what it was doing and came up with the av scanner
being called
like this:
<pathto>bdc --all --arc --mail <pathto>tmpdir.
(all means all files, arc
means to parse archives and mail to treat files as mail)
Its output shows that there isn't any virus. I got around to
make a copy
of the files that emerged after such an operation and issued
the *same*
command and bang: the scanner saw the virus.
Now of course a few of you will say there must be a
difference. Well
there isn't. I manually modified that script considering
that I'm either
stupid, sick or blind and can't see something. It just
doesn't perform
the same way. Well now I want to resolve the problem but
seem to be
missing a button...
Any thoughts?
