Bouncing vs. rejecting

Excluding MDAs, all MTAs forward mails to another MTA. This next MTA is
free to reject the mail with an SMTP error message like "user unknown",
"over quota", etc. At this point the sending MTA has to bounce the
message, i.e. inform its originator. A bounce may arise also without a
rejecting MTA, or as RFC 5321 puts it:

    "If an SMTP server has accepted the task of relaying the mail and
later finds that the destination is incorrect or that the mail cannot be
delivered for some other reason, then it MUST construct an
"undeliverable mail" notification message and send it to the originator
of the undeliverable mail (as indicated by the reverse-path)."
