Depending on your view point then it could probably be labelled any of 
those options.

I suspect you can hardcode the account to use port 993.

By default, MailMate tries both port 143 and port 993 if no explicit 
port is provided. MailMate then remembers the most recently 
(successfully) used port. This is probably port 993, but maybe this some 
times fails for reasons not related to the port number and then MailMate 
retries with port 143. This is when you see the error message.

The reason port 143 fails is likely that the port does not support 
STARTTLS which is how connections on this port are encrypted. I don't 
know why the server is configured like that, but one could argue that 
MailMate should handle it more gracefully.
