[MlMt] Handling expired PGP keys

[Steven M. Bellovin]

I composed a reply message to someone and requested PGP encryption and 
signature.  However, my copy of the recipient's key was expired.  I 
obtained a new version, but MailMate still insisted it was expired when 
I tried resending the draft.  I deleted the old key from my key ring, 
and tried stopping and restarting MailMate, but to no avail.  I finally 
copied all of the text from my reply message, deleted it, and created a 
new reply, pasting in the old text.  This seems to suggest that MailMate 
is caching the key on first attempt and not refreshing it, which doesn't 
seem right.  (I'm running 2.0 BETA 6074.)
