I would work around it as follows:  If the virus-scanner returns a tempfail,
then re-run the scanner only on the unpacked MIME parts and not the original
message.  The code would go something like this:

# ==========================================
# Copy original message into work directory
md_copy_orig_msg_to_work_dir_as_mbox_file();

# Scan
($code, $category, $action) = message_contains_virus();
if ($action eq 'tempfail') { # Oops... scanner choked
    # Remove original message from work dir - it might be causing trouble
    unlink('./Work/INPUTMSG');

    # And try again
    ($code, $category, $action) = message_contains_virus();
}

# Now deal with $code, $category, $action as usual.
# ==========================================

Meanwhile, I'd also file a bug with the virus-scanner company.  It
should handle the situation more gracefully.

David.
