I'm not certain, but this may be why MailScanner wasn't processing the
messages that were piling up in the Processing Attempts database.

I would suggest you forget the clamavmodule and just use clamd. It's way
more efficient anyway and you won't have to deal with this
clamav-wrapper issue. I think as long as clamd is running and
MailScanner's config has the default Virus Scanners = auto, MailScanner
will use clamd.

Those things are correct. The actual mktemp command at line 147 in
/usr/lib/MailScanner/wrapper/clamav-wrapper is

mktemp -d --tmpdir=${IWD}

The actual value of ${IWD} can be either
/var/spool/MailScanner/incoming/clamav-tmp or /tmp/clamav-tmp depending
on whether /var/spool/MailScanner/incoming is on a ramdisk or not, but
in any case it should be a "non-empty string", so I am at a loss to
understand what's happening here.
