Just as a side note (since Charles made his point very clear - to which I completely agree BTW): RFC 2821 is obsoleted by RFC 5321.
RFC5321 sec 4.2.4
the same wording about:
o if attempts to deliver the message fail due to permanent
conditions, or if repeated attempts to deliver the message fail
due to transient conditions, returning appropriate notification to
the sender of the original message (using the address in the SMTP
MAIL command).RFC3461 sec 5.2.6 Failure of a conforming MTA to deliver a message (referenced by both 2821 and 5321)
" (c) If no NOTIFY parameter was supplied for the recipient, a "failed" DSN MUST be issued. "
RFC3462 sec 1 (referenced by both 2821 and 5321)
" 1) [Required] The first body part contains human readable message. The purpose of this message is to provide an easily understood description of the condition(s) that caused the report to be generated, for a human reader who may not have a user agent capable of interpreting the second section of the Multipart/Report. "
And this sentence backs my argumentation, that a DSN should be in English (and probably in another second language), because an error message in human language XYZ only is not "easily understood". :)
Which comes down to Timo's original question, in order to remove the notification of Dovecot's deliver in favor of returning the proper exit code to let the MTA handles the stuff, seems to be good.
In order to handle Charles's idea, Dovecot deliver is to return "No error" and send no DSN in case of failure.
