Do explain how adding/replacing a valid Message-ID only to
submitted mail
will "break the complete mail handling of the client".
I mean replacing or deleting already set Message-Id headers. And it
will
break MUA driven thread handling and similar things which is based on
the original submitted ID.
And how do you
reconcile your last sentence with section 8.3 of RFC 4409?
Please read the RFC again. This sentence only speaks about _adding_
this
header, not about replacing or deleting it. There is however no other
point which allows arbitrary modifications to the messages.
There *is* mention of replacing and the replacing is not arbitrary.
The breaking of threading is interesting but irrelevant in my
particular case. Thanks everyone for the input.
