Broken email header handling by LP (here, causes strange barfmail)

[Ian Jackson]

See the attached message, which is clearly due to some bogosity.
I think that part of the problem is likely to be that Launchpad has
forged an email apparently from me to Barry Warsaw.

Below you will find the headers of my original mail in my FCC, the
mangled copy I got back from LP.

Problems with LP's email headers include:
 * LP failed to use Resent-*; instead it randomly permuted the
   originator and recipient headers (From, To, Reply-To, etc).
 * LP rewrote the charset to utf-8 unnecessarily, and encoded the
   message in quoted-unprintable, also unnecessarily.
 * LP deleted all of the Receved fields.
 * LP stripped out X-Mailer (so I assume it must strip out
   all other headers it does not understand).
 * LP has even changed the Date field !

This is wholly at variance with sane practice for handling email.

Ian.
