Where will this patch show up?  Since I'm running the standard issue
gentoo linux Mailman, I may want to apply it manually to the existing
code on my servers.  If you tell me what file(s) the regexp is found in,
I can probably make the code mod from what you've given me here.

Well you're probably right in this.  In this case, I can tell my
customer to be sure to only add ONE space between "Approved:" and the
password, since the double space triggered the error in this case.
Applying the fix you describe above will solve the problem going
forward.

This is well and good, Mark, except that in my experience there are very
few mail clients out there these days that enable the introduction of
arbitrary true message headers into an email, so this solution, while
ideal from the point of view of Mailman, is impractical in real-world
situations.  Most of my list hosting clients are pretty non-tech and are
using Apple Mail, MSOE, T-bird or something similar.  I'm using
Evolution, which is a cut above most consumer-grade mail clients, and to
the best of my knowledge it doesn't enable this.  The last mail client I
used which _did_ was mutt.
