[MlMt] Wrong SMTP

[John Doherty]

If you edit the IMAP settings for your fastmail account (File->Edit IMAP 
Account), is there an address pattern defined and enabled? That is, if 
dwpost.net is your domain, you might specify *@dwpost.net. Outgoing 
messages with From: addresses that match the pattern should use the 
outgoing SMTP server defined for that IMAP account.

Pretty sure that's how it should work, anyway, and it seems to in quick 
tests that I just did.
