Since a few weeks, I'm getting sporadic errors while trying to send mail with Thunderbird v2.0.0.22 (20090608) on Ubuntu Hardy.
I can send mails, but only sometimes. 4 out of 5 times, I get a strange error message like this:
(I've censored parts: xxx.xxx.xxx is a DNS name, and yyy some other provider-specific value)An error occured sending mail: The mail server sent an incorrect greeting: xxx.xxx.xxx yyy ... temporary failure.
It seems, that others are also having problems like that:

No SSL, no authentication, plain vanilla on port 25. hmpf.
Tech-support hotline said it's probably a timeout problem with my client.
Will finish this thread when I have found a solution.
