[Exim] Exim 4-MTA - Mailingslists - Newsserver

Hi,

I read about the possibility to use Exim to send mails coming from
mailingslists to an internal newsserver to get the mailinglist posts
in a newsreader such as outlook express where the mails show off in
threaded form - not just ordered by date like in a "normal" mail
program like notes... ;-)

Is something like this possible?
How could I achieve this? Are there any websites concerning this
problem?
Any hints, tips or infos are welcome!

Thanx,

Michael
