Although I know you're right (I'm operating a DNS by myself) I (just me,
personal) do not want to compare DNS-SOA and Message-ID as they are from very
different areas in network topology and used by very different protocol
stacks.
Also referring to RFC 2392 the message-id has to be in syntax a
'url-addr-spec' like described in RFC 822. There the syntax of 'url-addr-spec'
is specified as
<quote>
addr-spec = local-part "@" domain ; global address
</quote>
Unless the 'MyUsername' as wished by Roelof ain't a hostname it would not be
'formal correct' to use the period as delimeter. A second '@' ain't valid too
so unless his e-mail-address-domain ain't 'MyUsername.MyDomain.MyTLD' it would
not be RFC following to use it.
Of course I _do_ know nobody would feel disturbed if he does nevertheless but
as a good MUA tries to follow RFCs one can not expect it to (re)write message-id
in this 'false' way :-)
So the only solution I see is an own MTA that filters incoming mails from
internal for 'message-id' in header and rewrites it, but unhappily I don't
know of any that does this.
I could imagine of 'work arounds' or better 'expansions to existing MTA' e.g.
qmail but I don't think it's _really_ worth the effort :-)
Ciao Pit
