Dear Perdition list.
One of my clients have been having the following error happen continuously:
Your server has unexpectedly terminated the connection. Possible causes
for this include server problems, network problems, or a long period of
inactivity. Account: 'xxx.com', Server: 'mail.xcxx.com', Protocol: POP3,
Port: 110, Secure(SSL): No, Error Number: 0x800CCC0F
They are trying to POP about 105 messages but this appears after only
about 25. The above error would occur and then the same messages would
be downloaded again. Ad infinitum.
When I pointed the client directly to the mail server there was no
timeout so I think I can conclude that the destination server (Dovecot
POP3) is not the culprit.
My rough timings have shown that the connection dies after about 60
seconds which seems very telling.
My config is:
================================================
[root@tg1 perdition]# perdition --help

postfix-pop3.conf:

*Question*
What config should I be looking to change to ensure that large POP
downloads over slow connections do not time out?
Much thanks,
Daniel
