this is an known Problem with file + Debian Sarge. I think there is also
an bug report on http://bugs.debian.org/.
As a Workaround do the following:
# don't trust this file type or corresponding unpacker for this file
# type,
# keep both the original and the unpacked file for a virus checker to
# see
# (lookup key is what file(1) utility returned):
#
$keep_decoded_original_re = new_RE(
qr'^MAIL$', # retain full original message for virus checking
qr'^(ASCII(?! cpio)|text|uuencoded|xxencoded|binhex)'i,
qr'^gzip compressed data',
);
Add gzip compressed data to $keep_decoded_original_re . With this the
attached Virusscanner gets both original and decoded files and have to
look on this on his own.
HTH,
tim
