Hello, I have been comtemplating writing a pre-DATA hook into courier to allow for more efficient greylisting. I guess it would actually hook into the RCPT TO: handler. The biggest problem with the current method (in my opinion) is that it runs so late in the process, after having already recieved the message. It also uses hashes of the entire message, which seems to me to be a level of paranoia that will cause more problems than solve.
If each successful message stores remote address, sender email, and recipient email, a "2 out of 3" test seems pretty reasonable to me. Has anyone seen a situation where the MAIL FROM: changes on a retry? I'm thinking of things like mailing lists that automagically handle bounces, things like that. I'm interested in any comments or criticism.
