One thing missing is how to specify your mail address with each of
these systems. Am I wrong, or is it only Majordomo which supports this
(IMO, of course) _essential_ feature? I have to resort to faking mail
all too often.
Also, I think you should explain the role of request addresses! They
are not mentioned at all, and I think that there are at least as many
lists with a separate request address as there is LISTPROC and
PS. Fix your mail software so that it sends mail to the correct
address. The local part of the address should _not_ be tampered with.
