[Dovecot] PATCH: Deliver looses mail and DSN if Return-Path is missing

Hello,

Dovecot v1.0.0

if there is no Return-Path in the message and Deliver cannot deliver the 
message, no DSN is sent _and_ the MTA is returned 0 (aka success) return 
code, which leads to mail loss.

This is not the case, when the message actually finds a Return-Path, but 
fails to invoke the MTA.
