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
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
Maybe, the connections come in too fast.
