[Dovecot] lmtp multiple recipients fail

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:

We are using sendmail on a couple of MX boxes that are communicating
directly with dovecot/lmtp on port 24.  Again from the logs in my
first message the troubling entries are those that look like this:

Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Error:

backup.>: save failed to INBOX: Internal error occurred. Refer to
server log for more information. [2011-07-27 11:24:41]

lmtp seems to be attempting to write a link from one user's mail store
to another user's mail store.  This only happens on recipients that
are not first on the recipient list.

Best regards,
-Boris

PS - Apologies to the list if this mail produces an out of thread
message as I posted the original message as a non-member (needing
moderator approval) and I am now a member.
