I'm sorry if this is off-topic, but I believe your experience in this case
would really help me on. We are running Exim and QPopper on a Linux machine
and have finally figured out that it is QPopper that seems to have a memory
leak. Some clients generate errors that leave memory usage going steady up
until finally the server crashes.
Do you know any reliable and secure POP3 daemons that work with Exim 4? What
programs do you use?
