You need to set
ssl_min_protocol = TLSv1.2 # or TLSv1 Thanks, tried both, but unsuccessfully. Again, is there any debug setting that allows me to see what SSL version was requested? Without this, this is fumbling in the dark. In the german version of Apple Mail go to menu "Fenster" / "Verbindug prüfen".
There you can check the connection and log all transactions.
I don't know how detailed this is in older Apple Mail versions, but you could try.

Thanks Gerald, I'll try that. Strange though that the info isn't in the dovecot debug log.
Cheers,
