Henri, that does sound like it would work. The only thing to watch with your method, is that you block legitimate users that happen to key in the wrong address.
I've had great success with greylisting (glst from Davide). I did have to tweak it a bit to deal with the likes of hotmail/yahoo/etc because of their many sending MTAs.

I'll certainly look into it but I don't like the idea of having to run something in front of XMail... Also, I'd need to install Perl on my mailserver which is *strictly* a mailserver. > What you suggest might work, but spammers domains and addresses change > very rapidly, so I'm not certain you would actually cut down the > volume much, and you would end up having to process all of that email. > ASSP will simply terminate the session more or less immediately if it > doesn't like the email, the sender, or the address, or any combination > of those things. I don't have to process that much email though. First of all, my new CustMapsList filters out a lot of spam. If the sender seems ok, XMail first checks if the recipient is known. If not, it redirects it to my catch-all account. While it is doing that, the filters.pre-data.tab filter kicks in *before* the data command, only the headers have arrived so far. Next, my script will get the ip address from those headers and exits with code 3 which makes XMail to terminate the connection. Mail with a valid recipient will still go through the filter but that's not a problem. Sounds to me that it could work! ;) -- Henri. - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
