[MlMt] Specifying an "identity" per mailbox.

[Scott A. McIntyre]

Hi,

There's obviously some intelligence in how MailMate chooses the identity 
with which to send email from when composing a new message, but I've not 
quite worked out how to game it to work 100% the way I want - is there a 
way which I can specify a particular IMAP mailbox always has a certain 
default From address specified, possibly even PGP key to use?

Thanks,
Scott
