Summary: Broken PGP/MIME signature of messages with attachments
Initial Comment:
Hi,
When I send a PGP/MIME signed message *with*
attachments (in addition to the PGP signature) to a
Mailman-based mailing list, Firefox/Enigmail fails to
verify the signature of the message forwarded by mailman.
I have uploaded an example message with a broken
signature as attachment to this bug.
You can also see how Mailman's automatic archives don't
even handle such messages correctly by looking at how
it archived that message at:
http://sablecc.org/lists/sablecc-user/2004-December/000159.html
I've looked in the bugs database and found that a
somewhat related problem was reported a while ago, but
note that the current bug is different. The original
bug was about PGP/MIME signed messages without
attachments that were handled incorrectly by Enigmail.
This one is about messages with attachments, and it is
likely that the bug is Mailman's, at least accroding to
the reply I got in:
http://bugzilla.mozdev.org/show_bug.cgi?id=8466
Thanks for your help (and for the magnificient software)!
Etienne

Look at your content filter settings. What MIME-types are you configured
to pass? At the very least, you should be configured to pass the
following:
multipart/mixed
multipart/alternative
text/plain
application/pgp-signature
multipart/signed

I can reproduce this bug also.
Here's a diff what happened to me:
diff -u mail.valid mail.invalid
Content-Disposition: attachment;
filename=configure.in.pre-pkgconfig.patch
-Content-Type: text/x-patch;
name=configure.in.pre-pkgconfig.patch; charset=UTF-8
+Content-Type: text/x-patch;
name=configure.in.pre-pkgconfig.patch;
+ charset=UTF-8
Content-Transfer-Encoding: base64
And this was _inside_ gpg-signed block.
Mailman should not alter that section at all, right?
X-Mailman-Version: 2.1.4
Yours,
