I have setup amavisd-new with out email syatem which is currently using postfix, spamassassin, and cyrusimap.
I am currently using the free ClamAV virus scanner which seems to work well.
1) Does anyone else use ClamAV?
2) How good is it at detecting viruses compared to commercial products?
3) Are there any virus checkers you would recomend to run in addition to ClamAV?
I believe if you configure multiple virus checkers amavisd-new will check attachments against all of them?
