Kerberos support in Thunderbird

[ch0w]

This is the only thread I could Google that has anything remotely on
the topic of Kerberos-compatibility in Thunderbird. However, I'm having
a very difficult time following the thread discussion.

Thunderbird imported my Eudora settings (which works for me), but upon
"Get Mail" I always get the "Connection to server po11.mit.edu timed
out" error. In layman's terms, how can I fix this? Is it even fixable
in 1.5 beta 1? I've tried tweaking all the settings, even going to the
advanced:config menu, but can't seem to get Thunderbird to retrieve my
email.

Thanks.
