Hello all:

For several years I have been running the following in a Linux server.

Dovecot Version: 2.0.9

IMAP:
Connection Security: SSL/TLS
Port: 993
Authentication Method: Normal Password

SMTP:
Connection Security: STARTTLS
Port: 587
Authentication Method: Normal Password

The E-mail client is Thunderbird on Windows.

I am preparing a new server, with Dovecot 2.2.36 and would like to know the currently recommended protocols. Should I stick to what I have? I would prefer to start with the easiest configuration possible, which I will revise later.

This is the command that I have been using to verify the server's functionality:

% openssl s_client -connect localhost:imaps

TIA
