I am able to use secured SMTP for sending mail from Thunderbird to Xeams, but I can't seem to get the right settings for a  secured POP3 connection. Non-secure port 110 with "connection security=NONE" and "authentication method=Password, transmitted insecurely" does work. And, Xeams is not listening on port 995 as expected.

FYI, I do have 'Enable StartTLS' enabled on the server.

Thanks,

Tony
