How to configure Thunderbird (and other imap clients) for email at Southampton

I got the following information from isolutions in Feb 2013, and they seem to work (at that moment):

Please see below settings as requested.

Thunderbird

Incoming Mail Settings

Click Tools then Account Settings. Choose Server Settings on the left hand
side.

Server name: imap.exchange.soton.ac.uk
Port: 993
Username: Your username
Connection security: SSL/TLS
Authentication method: Normal password

Outgoing Mail Settings

Click the Outgoing Server (SMTP), then select smtp.soton.ac.uk outgoing
server and click Edit.

In Settings the description box can be left blank, the Server Name should be
smtp.soton.ac.uk and Port should be 25.

In Security and Authentication tick the Use name and password box, and in
the User Name box enter your username. Under Use secure connection select
the Start TLS option (not TLS, if available).

Authentication method: Normal password

Click OK.

Update September 2016 (thanks to Gary Downing):

While the most of the details above appear to be correct, for Thunderbird, one needs to use NTLM as the authentication method for the outgoing server.

Update September 2016 II (thanks to Pete Toshkov):

Sorry for the second email, but I only realised now that configuring the authentication method for the outgoing server (SMTP) using NTLM (as per the September 2016 update) doesn't allow me to send emails. I have to use Normal authentication instead.
