Right, but you insert 'Received: internal info suppressed', which is
plain wrong. The format of a Received header is descibed strictly
enough in RFC 5321, section 4.4, and 'internal info suppressed' is
far from matching that definition. Sure enough, one can insert into
message header whatever he wants, even a couple hundred lines from
'Alice in Wonderland' in a pinch. That doesn't mean, however, that mail
transport systems on the route will be able to digest the inserted
stuff. What's worst, you can never be sure what a mail transport system
would do if it is unable to make sense of your headers: pass the message
on or just drop it.
