Perhaps you can just change your sig to the nmh list to
--Dan
I doubt mail-archive.com hosting a few hundred lists would consider
interfering with the *body* of a message. Those who would like to
mangle perhaps at the list manager level, may also want to consider:
The Mail Archive utilizes two levels of electronic
countermeasures to prevent spam incidents. First, we explicitly
block spam harvesting robots (spambots) from accessing our
server. We deny access, at the server level, for any software
that matches the browser ID of a known spambot.
at http://www.mail-archive.com/faq.html.
In any case, those who do not want their message archived can always
add the header
X-No-Archive: yes
Hopefully, the nmh-workers list manager does not remove this (and
should not add it either if you guys decide to use mail-archive.com).
Finally, at mail-archive, they do not mangle, they hide the email
addresses from headers.
