Greetings,
We have many iOS clients, andomain.net some report that they’re having problems
with iOS mail copying messages to their Sent folder. This happens 2 - 3 times
per day, and the phone just says Sending and the client never knows if it
sends. Client says apparently email DOES go out, but there is no recording of
it. This is usually on our LAN.
We’re not sure if this is solved via Postfix or Dovecot, or maybe something
else, so I’m posting this message on both forums as a start. Can anyone point
us in the right direction here?
Running Postfix 2.11.1 and Dovecot ee 2.2.18.2
