[MlMt] Identities not right

[Randall Gellens]

This problem with the identities not being right is driving me crazy.  
MailMate used to be wonderful in showing me the identity that was being 
used, and in most cases automatically picking the right one.  The last 
update or three it's been terrible.  It no longer shows me the identity. 
  The only way I can get it to show me is the Format -> Show Identities, 
which often omits the identity I want to use (which MM used to determine 
from the address pattern and previous emails), and even when I use 
Format -> Show Identities and pick an identity, it is sometimes ignored 
and the message gets sent with a different identity.
