By changing the exiscan_av_scanner_regexp_trigger and
exiscan_av_scanner_regexp_description strings, along these lines:

exiscan_av_scanner = cmdline
exiscan_av_scanner_path = /local0/sophos/bin/sweep
exiscan_av_scanner_options = -archive -ss -all |
#exiscan_av_scanner_regexp_trigger = found in
exiscan_av_scanner_regexp_trigger = found in|Password protected
exiscan_av_scanner_regexp_description = (^.*found|^.*protected)

As you can see, this presupposes Sophos sweep.

Log entries now read like this:

2004-03-03 12:08:24 1AyVAc-0000SJ-GE rejected by exiscan(): This email
contains a virus, other hostile content or is an unscannable zip
file.\nVirus scanner reports: '>>> Virus 'W32/Mydoom-F' found'

or like this:

2004-03-03 12:34:59 1AyVaP-0001KH-BK rejected by exiscan(): This email
contains a virus, other hostile content or is an unscannable zip
file.\nVirus scanner reports: 'Password protected'

with the corresponding lines going into the rejection status.

Hope this helps.
