Hi,
I have a big problem with verification of detached PGP signatures when the
messages are read from the Exchange mail server (don't ask why Exchange - not my
fault - really). Exchange 2K changes MIME part description section for some
unknown reason from this:
Content-Type: text/plain; charset=iso-8859-2
Content-Transfer-Encoding: quoted-printable
which is generated by Gnus, to this:
Content-Type: text/plain;
charset="iso-8859-2"
Content-Transfer-Encoding: quoted-printable
which makes PGP signature verification (W s in summary buffer) fail. I guess
that the MIME header is part of the signed message. Can I do something about
this?
/S

What about posting your current PGG settings ? Without this, we really
can't do accurate debugging :) And so we just can't help you
more. Furthermore I am almost sure we can give you a quick dirty hack
to fix this temporaly at least ;)

Sure. These are my settings:
;; pgg settings
(require 'pgg)
(setq mml1991-use 'pgg
mml2015-use 'pgg
pgg-gpg-user-id "szak"
pgg-cache-passphrase t
pgg-passphrase-cache-expiry 600)

That could do :) Nevertheles I wonder why the MIME headers are verified along
with the message.
Thanks for response, /S

RFC 3156:
(5) As described in [2], the digital signature MUST be calculated
over both the data to be signed and its set of content headers.
^^^^ ^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
[2] is RFC 1847.

No, complain to your administrator or vendor that the server corrupts
your mail.
