I'm not terribly surprised.  mimelib is alpha-ish software, and I've
got some patches on my personal CVS server that I haven't released
yet.  I've just applied for an SF project named "mimelib" so if
approved, I'll be moving the code to a more public place (until and if
it ever becomes part of Python's standard library).

I wrote mimelib, 'natch.  Please send sample messages directly to me
and I'll run them through my current code base.  Also, let me know if
it's okay to add them to a PyUnit-based test suite that I'm going to
(eventually) add.

Thanks,
