[Savannah-hackers-public] Mailman generates invalid From headers

[Eli Zaretskii]

(If this is the wrong list to post this problem, please tell where to
redirect this.)

Mailman's rewriting of 'From:' addresses in GNU mailing lists
sometimes produces broken results.  Here's an example (from the
bug-gnu-emacs mailing list):

  From: "gliao.tw--- via "Bug reports for GNU Emacs,
   the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>

(These are 2 actual physical lines.)  As you see, the quotes don't
pair up.  The original address seems to be valid, judging by the
'Resent-from:' header:

  Resent-From: "gliao.tw@pm.me" <gliao.tw@pm.me>

Why does this happen?  Can it be fixed?

These unbalanced quotes cause Rmail in Emacs to format the inbox
summary badly.  I fixed Rmail, but the result is still sub-optimal,
and it would be good to avoid generating such invalid addresses in the
first place.
