Is there a way to move just the email account settings - no mail, no
contacts, etc - from one computer to another?

I've got two machines side-by-side. As near I can tell, all the settings
for my email account are the same on both, but one can send/receive email no
problem, the other sometimes only can receive after I send something,
sometimes can neither send nor receive at all.

I'd think the problem would have something to do with the firewall, but I
get the same problem whether or not the firewall is disabled.

So I'd like to try moving the account settings from one computer to the
other...
