[vchkpw] User defined black lists

[Anton G. Popov]

Hi all   Is there a technology with wich to allow users to create their own lists of senders they don't want to get mail from. The perfect behaviour of the server would be after it gets the mail from: and rcpt to: to check in a databse and reject the mail defore it arrives, if the rcpt and sender mach a user-defined pair. Or do I have to write this whole thing from scratch...   Thanks, Anton
