1. Verify that the mail messages in Mark's messages are handled correctly.
2. Decided what to do next :-).
If this problem has been fixed, then I think that the only thing we should do now is to change our recommendation from gnus 5.10 to 5.10.7. Please comment if you think additional documentation is required.

Subject: Gnus 5.10.6 problems with PGP/MIME (test cases)
X-Mailer: MH-E 7.85+cvs; nmh 1.0.4; GNU Emacs 21.3.1
Date: Wed, 11 Jan 2006 17:12:34 -0800
X-Mailer: MH-E 7.85+cvs; nmh 1.0.4; GNU Emacs 21.3.1
Background:
This problem arises using MH-E 7.85+cvs plus Gnus v5.10.6
running under GNU Emacs 21.4 on a Gentoo GNU/Linux box.
Problem (first message in attachment):
Content-Type: text/plain; charset="us-ascii"; format=flowed
does not properly allow the GNUS 5.10.6 mml-* functions to recognize
that there is a PGP Signed message body. If the format=flowed clause is
removed, then there is no problems with this recognition. I get this ';
format=flowed' addition to the Content-Type even for PGP messages that
are encrypted by Eudora users all the time.
Problem (third message in attachment):
Content-Type: application/pgp; x-action=sign; format=text
does not properly allow GNUS 5.10.6 mml-* function to display
the text or signature information. Note that I do understand that
this Content-Type is mentioned in RFC 2015 as being a bad idea.
However, I get this kind of Content-Type from some mutt users and
a few other Windows users.
The second message in the attachment decodes properly and will say
[[PGP Signed Part:Undecided]] until the user requests that the
signature be verified in which case it displays
[[PGP Signed Part:Mark D Baushke <mdb at gnu.org>]]
in the short form or
[[PGP Signed Part:Mark D Baushke <mdb at gnu.org>]

in the long form.
A similar set of problems arise when the PGP/MIME message is encrypted.
For the application/pgp form the encrypted Content-Type generated by
mutt looks like this:
Content-Type: application/pgp; x-action=encrypt; format=text
Please let me know if you have any questions.
Thanks,

I am not sure what to put for the gnus revision... and Katsumi didn't know
what to tell us to do either... I guess we could say that we have a patch
against gnus-5.10.6 that we put into contrib or something...
A possible etc/MH-E-NEWS entry might be:
* Changes in MH-E 7.90
...
** Bug Fixes in MH-E 7.90
...
*** mh-mime-display and mh-mm-inline-message
These functions have been enhanced to use mm-uu-dissect-text-parts to
deal with more kinds of encapsulated MIME types. This, in conjunction
with a patch to gnus-5.10.6 or an unpatched gnus-5.10.7 or gnus-5.11
will allow OpenPGP encrypted or signed email in a format=flowed text
Content-type to be properly recognized.
It is late, and I am not sure I like what I wrote, but you get the idea
of what you can say...
\-- Mark
