Default POP3 and IMAP stop respond

I have Postfix + Courier-POP3/Courier-IMAP configured on Debian etch.
From times to times POP3 and IMAP stop working.
This is the case now that when I try to use POP3 I get the following alert: Connection to mail timed out or Your POP3 server does not respond
When using IMAP I get the following: Login to server failed

The system was working normally two days ago and no changes where made in configurations.
Could someone help getting out from this?
Thanks.

Any errors in your mail log?
Do you still see them in the output of
Code:
netstat -tap
when this happens?

You could install monit to watch and restart Courier: http://www.howtoforge.com/server_mon...debian_etch_p2

I found it was a DNS conflict and probably it was the same reason every time the error occurred. Anyway I believe it will be useful to install monit. Thank you for helping.
