Stuttering KMail + WM Selection

[Robert Tilley <tilleyrw@tillarium.debian.org>]

Two issues here:

1 -- The Debian-KDE mail server appears to be "stuttering" the e-mail it 
sends out.  I received two copies of each individual e-mail on the list.

2 -- When KDM appears on my screen, there is no choice of which window 
manager to use and if Default is selected, Blackbox begins.  Although I can 
still use the KDE apps, I lose the cohesive environment that KDE is meant to 
provide.  Which config file do I edit to add more window manager choices to 
the KDM drop-down menu?

I understand that KDE is wm agnostic.  Is this a wise move?  I am seeking a 
KDE config that is faster that the normal install.
