Hi William.

First, I just want to be sure you're running the test suite the way  
it's (currently) intended.  Here's what I do in a pristine branch:

% mkdir staging
% pushd staging
% export PYTHONPATH=`pwd`:$PYTHONPATH
% popd
% python setup.py develop -d staging
% staging/bin/testall lmtp

You might want to run testall with -v and/or -e.  The former produces  
a bit more verbosity, such as the config file its loading.  The latter  
propagates any exceptions in the child process to the console.
