i do think some sort of smtp-callback would be nice/useful for validation of e-mail addresses. it'll make it so the bounces go to someplace at least instead of Postmaster.
The fact that you can call back in no way means that bounces won't double-bounce into the postmaster mailbox. I'm sure that yahoo.com would buy into a callback scheme, but it wouldn;t have done squat for this double-bounce: ----- Transcript of session follows ----- ... while talking to mx1.mail.yahoo.com.:
DATA <<< 554 delivery error: dd Sorry, your message to xxxxxxxx@yahoo.com cannot be delivered. This account is over quota. - mta461.mail.yahoo.com 554 5.0.0 Service unavailable
(OK, so THIS double-bounce was a W32/Klez-H generated one, but I get enough of the same thing for spam with a Yahoo return adress). -- Valdis Kletnieks Computer Systems Senior Engineer Virginia Tech
