I have been running Courier 0.39.1 on Debian Linux as my mail server
(SMTP(S), POP3(S), IMAP(S)) for about a year now without any noteworthy
problems. Today, the SMTP server started to act up: it accepts TCP
connections virtually immediately, but then reacts only very, very slowly.
Thus, most of the time, the connection times out on the client/peer side.
Other services (POP3, HTTP, ...) work as perfectly as ever.

for about 5 min or so, after that time it works again until the next 5
problem minutes.
I've tried to narrow the problem down.

greeting. I've tried it from 5 computers (everyone in a other subnet and
other dns servers) always the same. on localhost it works always.
