calling password lost

[plopsdad]

Have a remote post office having a issue with the password to call into post office to send / receive. To make a long story short, it will not accept incoming calls from my main mail router because it says the password is incorrect, and wont call because it says password is incorrect.

I have Admin post office password and that works find, but if i try and change the CALL POSTOFFICE PASSWORD it says "cannot change password".I try via ccamil client and admin gui tool, same thing, any clues????
