When Courier is sending or receiving mail from them?
Yes.
Which one?
Sometimes when sending and sometimes when receiving.
0.32.0 of 28.02.01, but there was no significant changes in that respect
in
comparison with previous versions. Looks like these overloaded servers
introduce some delays in ESMTP communication with courier and its
reaction
is not always adequate. Unfortunately it's very difficult to catch these
situations - they are absolutely stochastic.
I'm wondering if Courier times out while sending mail to them, the socket
gets closed, but then, for some reason, it tries to write something to the
closed socket...
Could you advise me how to find out what really happens?
stracing the process is really the only way. You could attach strace to the
listening couriertcpd process, with the -f flag. Then, once something got
deferred, stop the trace and go back and find the actual process in the log.
Make sure you have plenty of disk space.
