can't change outgoing mail server with lepard

[Jed Barton]

Hey guys, sorry to be a pain, but yet another lepard issue.  I'm  
trying to change my outgoing mail server.
It says outgoing mail server combo box.
I can not for the life of me get to a combo box, and i have no idea  
how to interact with it with lepard. I've never seen a combo box  
before with it.
Any ideas?
Thanks,
Jed
