Thelv,
Here is what I have in my amavisd.conf file:
@av_scanners_backup = (
['Clam Antivirus - clamscan', 'clamscan',
'--stdout --disable-summary -r {}', [0], [1],
qr/^.*?: (?!Infected Archive)(.*) FOUND$/ ],
);
The way I understand it is that if amavisd can't find the daemon (which it
didn't in my case), or any other daemonized AV programs that are listed,
then it will use the "backup" scanners. So, it will call clamscan for each
email that comes through. I would assume that this would cause (possibly
significant) overhead on a busy mail server - but my mail server is not busy
by any stretch.

I guess I am unsure how the command line as backup works. I had configured
the amavisd.conf file in the av scanners. This we both agree on does not
work. I then commented it out and let the next group (backup scanners) to
find the clamd and run that way. I am assuming that is what your talking
about. Or are you talking about starting clamscan another way. Sorry just
a little green on the clam. I am wanting clam to scan the email. Thanks.
