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:
