Re: [clamav-users] can I check for CreditCards but NOT check for SSNs?
Well, I feel dumb now... not sure why I didn't try that before. Thanx Mickey! Rob.

Hi, this is not setting of clamav itself. It should be configurable in SMTP server or its antivirus interface like Amavis. Clamav just decides if the file is infected or not. It is the SMTP server that decides what is sent back. Ah, ok. Thank you for pointing me in the right direction! On the other hand, you shouldn't be sending bounce messages at all (assuming you are using the correct terminology). It is much better to reject unwanted emails. Bounce - Your MTA accepts the message, determines that it's not wanted, and sends a message back to the sender. Reject - Your MTA determines that the message is not wanted before accepting it from the sending server and returns an error to the sending server. It is then up to the sending server to determine what to do with the message. Once your MTA accepts the message, you have no reliable information about the sender of the message. Any bounce message you send is not guaranteed to go back to the real sender of the message. This can turn your server into a source of bounceback spam. It is much better to simply reject the message and let the sender deal with it. Legitimate messages will still have a bounce message sent from the sending server and you don't have to worry about your server sending a pile of bounce messages to an innocent third party whose email address is being used by a spambot. Thanx! Guess I used the term bounce incorrectly. After looking at my amavisd.conf file, I realized I have: $final_virus_destiny = D_REJECT; So it is properly configured, just not behaving the way we want it to yet.
