They do NOT have a 'right' to do this. If they want to run a mail server, they need to learn the basics, and engaging in backscatter is NOT acceptable. Most DLS-based (dynamic IP's) mail servers will have a huge problem sending and receiving mail from legitimate mail servers anyway, because they are by default on lots of black lists. For this reason alone, it is highly recommended to NOT run your own mail server from such a connection. > ASSP and Sendmail know for which domains they are relaying, but not > which user.

If I were you, rather than spend time fighting a tornado, I'd spend time fixing the actual problem... figure out a way to get ASSP a list of valid recipients, or, best case, learn how to configure sendmail to pass-thru the VRFY request to whatever server DOES know the list of valid recipients, and simply let ASSP use its own internal VRFY command. And simply make it a policy that any customer of yours who wants to host their own email server MUST use recipient validation. -- Best regards, Charles ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
