Description of the change

It probably needs a little more work before merging.

Open questions:
1) Is the test naming okay?
2) Should the tests be done in a different way? I didn't find any other tests that used the mock library.
3) Should the mocking be done within the setUp stage?
4) If that's okay, should get_mocked_lmtp_channel be moved to tests/helpers.py?
