In general trying to do all of this in the MTA is a mistake. Get one of
the mailing list managers and use that - they should all work with exim
(unless specifically written for something else).
There is a very old FAQ on mailing list managers (cannot find a more
recent copy) at
ftp://ftp.uu.net/usenet/news.answers/mail/list-admin/software-faq
People are using smartlist and majordomo with exim with apparent success.
