tlslite doesn't work with Python 2.5 and up, and the patched version
seems to be a myth -- when I checked it, there were no actual
differences.

It's not clear there's any Python version issue here, but I can't say
for sure. It looks more like the IMAP server that's supposed to
authenticate the user is not available.

This is the familiar problem with tlslite and Python versions that are
less than five years old. I explained it in some detail here:

http://article.gmane.org/gmane.mail.spam.tmda.devel/6820

And I eventually followed up with a modified TMDA that uses OpenSSL
instead of tlslite:
