[MlMt] TLS 1.3 supported?

[Frederik Schwan]

Hello MailMates,
I installed MailMate quite recently on my new Mac.

Though I run into connectivity issues. The server gives me:
> SSL_accept() failed: error:0A000102:SSL routines::unsupported protocol

MacOS itself supports TLS 1.3 and the installed OpenSSL version does as well.

How is the status of TLS 1.3 support for MailMate? I've set my server's SSL config to TLS 1.3 only over a year ago
and had no issues with Thunderbird, Mail.app nor any Linux-specific tools.

Thanks in advance,
Frederik
