Here the relayhost seems to be using a content filter, and on the line above is reporting what it has heard through the filter. It also reports the queue ID on the other side of the filter, to wit: "08DEC26AEC71". > Feb 18 17:32:52 pi postfix/qmgr[21159]: 2009B22C52: removed > > > > On the system that appears to send OK but the message never > reaches its destination I see:- > > Feb 18 18:32:18 odin postfix/pickup[15648]: 05E963BC3: uid=1001 > from=<chris> > Feb 18 18:32:18 odin postfix/cleanup[15989]: 05E963BC3: > message-id=<20170218173218.05e963...@odin.zbmc.eu> > Feb 18 18:32:18 odin postfix/qmgr[14084]: 05E963BC3: > from=<ch...@zbmc.eu>, size=296, nrcpt=1 (queue active) > Feb 18 18:32:19 odin postfix/smtp[15991]: 05E963BC3: to=<ch...@zbmc.eu>, > relay=mail3.gridhost.co.uk[95.142.156.18]:587, delay=1.2, > delays=0.22/0.11/0.65/0.19, dsn=2.0.0, > status=sent (250 2.0.0 Ok: queued as EDA7EE0C39) Here we didn't get anything from the content filter. The answer of the question, "Why not?" is probably in the logs on the relayhost. > Feb 18 18:32:19 odin postfix/qmgr[14084]: 05E963BC3: removed > > > Does that 'queued as EDA7EE0C39' in the second case mean that the > message has been put on a queue rather than being sent?
