Should single instance store work in the following scenario:
A message is addressed to two accounts. It is delivered to one successfully
but the other a/c is over quota so delivery fails and the message remains in
the mail queue. The quota limit is then bumped up for this a/c, the MTA
retries delivery and succeeds.
I tested this but single instance store wasn't used in this case. The question
is: should it? The setup is Exim using LMTP over a unix domain socket. Single
instance store does work in my setup when there are no delivery errors just
not in this situation.
