Recommended Protocols?

[Raymond Herrera]

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
