Figure out:
I'm working with the MUA, when checking mail of different incoming folders 
the connection (or better to open a new folder) becomes very slow or times 
out. I do use another MUA for different things, which cannot connect at 
all.

At this time I ssh to the mail server and telnet to local port 143. I get 
a connect ("Connected to localhost"), but no greeting. When I keep the 
telnet open, nothing happens. There is no greeting, even if the server 
gets back into "normal" state, the telnet session simply stays so.

This is a) worth a try and b) not that bad anyway, because we have several 
times a day about 30 users are instructed to read their mails 
simultaneously.

Maybe, the connections come in too fast.
