Mail app won't recognize Cloudron's TLS support
I can't connect Nextcloud's mail app with my Cloudron mail server. I've configured it according to the docs, but when I try to connect to the server an error pops up: "Creating account failed: Server does not support TLS connections.".
Does anybody know if it could be the app or Cloudron's issue, or am I doing something wrong? I can send and receive e-mails with the same configuration using my phone and K-9 Mail.
