Maybe that a draft is not a normal article is not a direct cause
of your problem.  Though I haven't yet investigated why sometimes
it fails with the message "Selecting deleted buffer".

Sorry for my funny English.  I meant that it will take time (IOW,
cost me time ;-) to improve the Lisp code so as to transform
a draft message, that is copied or moved to a normal group, to
a normal article.

I have another idea.  That is to make the behavior of expiring of
drafts be always `delete' no matter what nnmail-expiry-target is.
It lets you and friends have no need to have such a special group
parameter.  Ones who want to have a local copy of a sent message
can use Gcc, that saves it as a normal article.  WDYT?
