[MlMt] Editing learned recipients.

If your Sent Messages mailbox is empty then MailMate only looks in 
Contacts when doing completions. (At least this is the default 
behavior.)

How can I specify a different mailbox? And how can I modify the default 
behavior? For example is it possible to create a smart mailbox that 
would contain whatever is specified by a set of Rules, and instruct MM 
to use that mailbox as a source for completions?
