[Dovecot] lmtp multiple recipients fail

[flylordis flylordis]

Hello,
I am having a problem with the lmtp delivery of mail addressed to
multiple recipients.  The first recipient receives the mail correctly
but the next recipients do not.  ltmp apparently tries to create a
link from the subsequent recipients' mail store to the first recipient
mail store and fails.  This returns 451 smtp codes to the sender which
then resends at some later time.  Please see below for users jerry,
steve, and mary.  The message to jerry gets written but not steve or
mary:
