Re: sends notifications

[natan]

Hi

Thenx from replay Wietse

Probably I limited or disable like

/etc/postfix/main.cf: smtpd_discard_ehlo_keywords = silent-discard, dsn

because I have problem with one MTA (not my) who ask DSN when send e-mail to me (send 15 and more to me per h) and my MX answers him about delivery (sucessfull) and external MTA limited me (5 delivery for h) and my queue grow

Success notifications are normally requested by the sender:

    MAIL FROM:<sen...@example.com> NOTIFY=SUCCESS,FAILURE,DELAY

As defined in https://tools.ietf.org/html/rfc3461#section-4.1

They may also be sent when the Postfix sendmail command is called as

    /path/to/sendmail -N success,failure,delay

This can also happen after content filtering.

Finally, the success notifications may be sent when Postfix is
configured to append "NOTIFY=SUCCESS,FAILURE,DELAY" ot MAIL FROM
commands as described in
http://www.postfix.org/postconf.5.html#smtpd_command_filter.  This
can also happen after content filtering.

You can limit the scope of success notifications with
http://www.postfix.org/DSN_README.html#scope
