When Thunderbird tries to send email it goes through three steps you 
which you can follow on a little pop-up window:
- connecting to server
- connected to server
- sending email
It gets stuck on the first message, meaning that it doesn't actually 
connect to the server at all.

Awesome idea.  I'll see if I can catch it next time.  Although, the 
Wireshark filters should negate the need to stop all other programs.

Interesting idea.  I'll try that, it should be a static server after 
all.  Didn't you mean "Thunderbird"?
