Well I got the OpenSSL parts working now, but newer versions still refuses to
work after establishing with ECDHE, I just get no login attempts and no user:

imap-login: Info: Aborted login (no auth attempts in 0 secs): user=<>,
rip=55.66.77.88, lip=11.22.33.44, TLS, TLSv1.2 with cipher
ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)

iOS 13 definitely works with dovecot; it?s how I am able to send this mail.

My main job is trying to come up with new and innovative and effective ways to
reject even more mail. I'm up to about 97% now.

That did it, must have changed it while debuting this and it continued to work
on MacOS but not iOS.

Thank you!
