I think you're mixing with Return Reciepts. Mail recipients do not play a role in DSN delivery, MTAs do, and in fact, it's not even on the recipient side, but on the sender side, in which case you receive something like this: "This is the mail system at host [...] Your message was successfully delivered to the destination(s) listed below. If the message was delivered to mailbox you will receive no further notifications. Otherwise you may still receive notifications of mail delivery errors from other systems. The mail system <x...@yahoo.com>: delivery via mta7.am0.yahoodns.net[67.195.228.109]:25: 250 ok dirdel" Best, -- yassine -- sysadm +213-779 06 06 23 http://about.me/ychaouche Looking for side gigs. _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
