Make sure you use the beta available at https://freron.com

If you still have an issue then contact me off list and I can test by connecting to your server.

MailMate uses the CFNetwork framework (since r5263) which, as far as I know, supports 1.3, but there could of course be a configuration issue that I'm unaware of.

Ideally, MailMate should switch to Apple's Network framework, but that requires macOS 10.14+ (MailMate is still 10.12+). Yes, “maintaining” software often requires completely replacing existing code because of system changes :)
