Did it say that they were password protected?
Clamavmodule can also choke if they are over it's stated limit on how
compressed the file is.
Look in this area of conf;
# ClamAVModule only: set limits when scanning for viruses.
# The maximum recursion level of archives,
# The maximum number of files per batch,
# The maximum file of each file,
# The maximum compression ratio of archive.
# These settings *cannot* be the filename of a ruleset, only a simple number.
ClamAVmodule Maximum Recursion Level = 10
ClamAVmodule Maximum Files = 1000
ClamAVmodule Maximum File Size = 10000000 # (10 Mbytes)
ClamAVmodule Maximum Compression Ratio = 950
MailScanner is like deodorant...
You hope everybody uses it, and
you notice quickly if they don't!!!!
