Control Panel weirdness in System - Server Config

I am using The Perfect Server - Debian Lenny (Debian 5.0) With MyDNS & Courier [ISPConfig 3] setup and everything has been running fine for quite a while.

I was looking around in the control panel today and noticed that under System - Server Config - Mail it showed Dovecot and Sieve instead of Courier and Maildrop like it should have. I have since changed it to reflect the correct settings, but I am curious as to what this page actually indicates, because it was incorrect but caused no errors.

It almost made me question which debian perfect server tutorial i had used!

Another question is on the DNS tab, everything says BIND but I am using MyDNS.

Thanks in advance for any answers.
