Okay, thanks for the plentiful reasons to not make the assumption of

Yep, I know that the gnupg.org lists have some configuration problems
that need fixed.  In the above I mean that I plan to contact the folks
who author Werner's MUA, Gnus (a mail client inside of Emacs -- and
here I thought Emacs was just an OS ;).  Sorry for not making that
clearer, I realize that mixing a discussion of GnuPG and Gnus can get

In addition to changes to the gnupg.org config, it could be helpful if
Gnus added content-type headers, as lacking them is what caused
Mailman to totally skip the first part in Werner's message.  I'll wait
to see what you and Tokio come up with to fix that within Mailman, but
it shouldn't hurt to mention it to the Gnus authors, as I know there
are many, many email parsers out there that are much less thoughtfully

those types of issues.  I first wanted to square away any potential
Mailman bugs so that I could add "apply the patch referenced in this
thread on mailman-users" in addition to suggesting some config

That is a hard choice to make - break any external links to your
archives or fix the broken internal ones by wiping and recreating
them.  I don't doubt that it'll get solved at some point though, after
reading the thread here a week or so ago.

Indeed.  You helped track down and fix a small bug in the handling of
pgp/mime messages that included attachments not long ago.  As usual,
your patient and persistent help is very much appreciated!
