So you say that kmail uses AUTH LOGIN, and that AUTH PLAIN fails?

This indicates that your mail server is misconfigured or buggy: if it
first says that it supports AUTH PLAIN, but then refuses to accept you
when you use it, you should verify that the mail server works
correctly.

Yes, this is the server certificate that it asks you to accept. Python
accepts it silently.

Hard to tell. You can try to use a different mail server, or you can
try to use Python 2.2.2, and change preferred_auths to list AUTH_LOGIN
first.
