Key e-mail delivery concepts

Relaying: When an e-mail server (MTA) forwards submitted mail to another server for delivery

Queueing:  a filed delivery or relay attempt is queued and retried periodically by the MTA(By default Postfix does this once every hour.)


Rejected: when an e-mail message is refused by an e-mail server during the initial submission

Bounced: when an e-mail message is returned by a remote server to the originating e-mail server and/or user after it has been accepted for delivery by the remote server
