[exim] Duplicate email removal in Exim-filter?

Hi there,

probably I just did not google for the right words...

So here is a simple question:

Is it possible to remove duplicate messages sent via Mailinglists
and as a personal copy be means of message-id comparison in an
exim-filter?

I did this using procmail/formail a long time ago.
