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

[fwstyle]

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.
