Ok "solved" by adding Login to AuthMechs field in configuration file.

@ossi Thank you very much for the quick response. So this is probably related to changes on my email provider's (Fastmail) side? Why AuthMech might stop working at some point? Sorry I don't know what AuthMech or X0AUTH2 mean so just trying to research what I should actually do to fix this.

Error performing SASL authentication step: SASL(-1): generic failure: Unable to find a callback: 18948

OK got it and confirm your fix does indeed work. I managed to compile on my macOS system by doing following Have homebrew package installed Replace macOS's openssl version with provided one from hombrew: brew install openssl && brew link openssl --force If you get console warning that you need to add it to your PATH, do that, link openssl --force again and reload terminal session. Then copy the files like this: cp /usr/local/opt/openssl@1.1/lib/pkgconfig/*.pc /usr/local/lib/pkgconfig/. I found it...

By that package do you mean openssl-dev? I'm on macOS so I tried searching for openssl-dev / openssl-devel but no luck.

@ossi One more thing. I've tried pulling 1.4 branch, read the instructions for installation. I wanted to check out if it works with your changes. However did something change between 1.4.0 and what is currently in that branch as far as configuration goes? I've got error saying that SSLType and SSLVersions is not supported within IMAPAccount section.
