Default courier-imap/pop3d not work with listening to all address

Hi everyone!

I have follow The Perfect Server - Ubuntu 9.04 [ISPConfig 3] and everything works fine exacpt courier-imap/pop3d.

The problem is simply cant access imap and pop3 from external host while working fine with squirrelmail. And I check netstat the port listening correctly.

Base on trial and error, i changed the ADDRESS to single IP and it just work immediately.

My server have 2 IP run on same interface. Actually i am ok with accessing pop3/imap with 1 IP only. Just after my ad-hoc solution ISPConfig Monitor state my pop3 server not running correctly.

Anyone have the same issue and please suggest the right solution.

Looks ok. And it's working if you specify an IP in your email client, but not if you specify a hostname? That sounds as if the DNS record of the hostname is pointing to a wrong IP.
