Here is a sample. The term "Blocked" is used. Does ClamAV scan the files looking for viruses or just it just wholescale block them?
Amavisd, using clamAV has a series of decoders. Hence my question.
### BLOCKED ANYWHERE
# qr'^UNDECIPHERABLE$', # is or contains any undecipherable components
qr'^\.(exe-ms|dll)$', # banned file(1) types, rudimentary
# qr'^\.(exe|lha|cab|dll)$', # banned file(1) types
### BLOCK THE FOLLOWING, EXCEPT WITHIN UNIX ARCHIVES:
# [ qr'^\.(gz|bz2)$' => 0 ], # allow any in gzip or bzip2
[ qr'^\.(rpm|cpio|tar)$' => 0 ], # allow any in Unix-type archives
This is completely unrelated to ClamAV or virus scanning in general.
There is a amavis-users mailing list you might check out.
