You're using mailx -v, therefore Postfix will send you an email message with a summary of the delivery. I'll get back to that later. Fist the message submitted with mailx -v: > Aug 13 14:37:55 u0 postfix/pickup[6727]: C630B180CB9: uid=1000 > from=<reader> > > Aug 13 14:37:55 u0 postfix/cleanup[6746]: C630B180CB9: > message-id=<20170813183755.C630B180CB9@u1> > > Aug 13 14:37:55 u0 postfix/qmgr[6728]: C630B180CB9: > from=<rea...@u0.local.lan>, size=1374, nrcpt=1 (queue active) > > Aug 13 14:37:56 u0 postfix/smtp[6748]: C630B180CB9: > to=<hp...@fastmail.fm>, relay=smtp.fastmail.com[66.111.4.139]:587, > delay=0.67, delays=0.12/0.1/0.36/0.09, dsn=2.0.0, status=sent (250 2.0.0 > Ok: queued as 5A0A57E317) The message was delivered to smtp.fastmail.com. Then, Postfix sends an email with summary of what happened: > Aug 13 14:37:56 u0 postfix/cleanup[6746]: 6943A180CBB: > message-id=<20170813183756.6943A180CBB@u1> > > Aug 13 14:37:56 u0 postfix/qmgr[6728]: 6943A180CBB: from=<>, size=1939, > nrcpt=1 (queue active) > > Aug 13 14:37:56 u0 postfix/bounce[6750]: C630B180CB9: sender delivery > status notification: 6943A180CBB > > Aug 13 14:37:56 u0 postfix/qmgr[6728]: C630B180CB9: removed Where is the rest of the logging for 6943A180CBB? As for this: > Undelivered Mail Returned to Sender > > > The mail system > > <hp...@fastmail.fm>: Cannot start TLS: handshake failure > > with an attachement that says: > > Reporting-MTA: dns; mailauth.nyi.internal > X-Postfix-Queue-ID: C44B420EF3 That is UNRELATED to the logging above. It was sent by a mail system that calls itself mailauth.nyi.internal. To find out more about message C44B420EF3, ask the owner of that system what happened with message C44B420EF3. Wietse
