Ah NOW I understand. You mean the final delivery of a bounce generated by
any other MTA to the sender of the erroneous message (the sender has
a cyrus imap mailbox). Yes then you are right, I think this is a bug.
There should be some matching for "<>" as Return-Path in lmtpengine.c, because
this is the only correct Return-Path for an automatically generated bounce
message... :(
