Hi,
Have anyone else experienced problems using Dovecot with the mail app in beta releases of iOS/iPadOS 13?
TLS is failing for my, it have worked fine for years and I am on the latest Dovecot version now, it works fine with older clients but not with the ones upgraded:

Anyone seeing something similar and/or have suggestions on how to proceed?

Just a wild guess as I didn’t try to configure Mail on Catalina yet, but it looks like your server only supports ‘DHE-RSA…’ ciphers. I think that modern systems prefers using ECDHE key exchange and would not be surprise if iOS requires it.
What version of OpenSSL are you using ?

An interesting note from the Apple documentation about what is considered a secured server:
• The link must support perfect forward secrecy (PFS) through Elliptic Curve Diffie-Hellman Ephemeral (ECDHE) key exchange.https://developer.apple.com/documentation/security/preventing_insecure_netwo... https://developer.apple.com/documentation/security/preventing_insecure_netwo...

A good guss, I am using 1.0.2r, but it is missing ECDHE so that seems like the problem. I will try with a openssl that supports it.
Thank you!

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:
