Rcpt To Relay Access Denied
SMTP server to block a sender (MAIL FROM) or recipient (RCPT TO) address postfix relay access denied until the address has been verified to be deliverable. The technique has obvious uses to reject junk mail with "recipient address rejected: access denied" an unreplyable sender address. The technique is also useful to block mail for undeliverable recipients, for example on a mail relay host that does not have a list of all the valid recipient http://serverfault.com/questions/266237/postfix-rejecting-to-address addresses. This prevents undeliverable junk mail from entering the queue, so that Postfix doesn't have to waste resources trying to send MAILER-DAEMON messages back. This feature is available in Postfix version 2.1 and later.

The preferred MTAs could include the Postfix MTA itself, or some remote MTAs (SMTP interruptus). Probe messages are like normal mail, except that they are never delivered, deferred or bounced; probe messages are always discarded. -> probe message -> Postfix mail queue Internet -> Postfix SMTP server <-> Postfix verify server | v <- probe status <- Postfix delivery agents -> Local -> Remote ^ | v Address verification database With Postfix address verification turned on, normal mail will suffer only a short delay of up to 6 seconds while an address is being verified for the first time. Once an address status is known, the status is cached and Postfix replies immediately. When verification takes too long the Postfix SMTP server defers the sender or recipient address with a 450 reply. Normal mail clients will connect again after some delay. The add
