These are MailScanner errors, you should really post them to the
MailScanner list. The unrecognised line errors don't matter (just
unexpected output that is being ignored, however the 'no files to
extract' is probably a symptom of running clam as root. It tries to use
/root/tmp as temporary space - but because it drops privileges it cannot
write to there. I've attached my own updated clamav-wrapper which
addresses this issue. You will need to uncomment the lines about unrar
in it.

# Modifications by Kevin Spicer <[EMAIL PROTECTED]> to get
# external unpackers working correctly. 9 Nov 2003
# Removed --unzip from ScanOptions, as its already in ExtraScanOptions
# (Clam usually uses own unzipper, -unzip just allows it to use external
# program so should be in ExtraScanOptions as it could cause a failure)
# Separate all unpackers and add missing ones.
# Add tmpdir (and check for it) in MailScanner incoming dir
# (to take advantage of ramdisk) - needed by external unpacker
###### IF YOU ARE RUNNING MAILSCANNER AS ROOT ######
# You need to set the following in MailScanner.conf so that external
# unpackers can be used...
# Incoming Work Group = clamav
# Incoming Work Permissions = 0640
# You may want to check this script for bash-isms

# Extra options we try to pass to clam but we handle it failing
# For each option there are two alternatives...
# --option # if the required program is in the PATH
# --option=/path/to/program # If its in a non standard location
# If you use the second option make sure you set the correct path in each case
# Note that clam internally supports Zip, Gzip and Rar (v2.0) files,
# so for these the extra options are just a fallback should the internal
