Unique token for message approval

[Wyardley]

I requested this on mailman-users; going ahead and
submitting as a feature request as per your request on
the list.

It seems like it would be nice to setup a method of
confirmation for *approving* messages that uses a unique
token instead of the list password; while (hopefully) in
most cases, the moderator will be sending approval messages
over SSL or from the same machine the list is on, it seems
like a bad idea to make the confirmation token the list
password (especially in case you accidentally add the
'Approved:' header to the wrong message, or in case someone
spoofed a message appearing to be from Mailman in order to
try and scam list passwords)....

How about generating a unique one time password and having
people add this to the Approved: header? This would make it
much harder for someone to accidentally disclose the list
(or worse, site) password.
