Big reconfigure problem/challenge

Hi!
I'm facing a major remodel of my systems due to a very restrictive ISP.
They've suddenly announced that they'll block all traffic on port 25,
which will have a huge impact on my 30-domain, 400 mail account systems...

Anyway, what I'm looking at trying to do, is to have a mail-forwarding
system (like ZoneEdit or similar) that forward all mail to one account
at the ISP server, and then have my Postfix server poll that for mail,
and in my end, sort everything up to the correct recipients.

Is it at all possible? A mail-forward from a ZoneEdit server can look
like this:

Received: from mail6.zoneedit.com (mail6.zoneedit.com [66.240.226.247])
        by mail.the-server.net (Postfix) with ESMTP id 7B8F314333
        for <mailpoolnorrbring.se>; Mon, 28 Jan 2008 08:32:28 +0100 (CET)

Received: from web25613.mail.ukl.yahoo.com (web25613.mail.ukl.yahoo.com
[217.12.10.47])
        by mail6.zoneedit.com (Postfix) with SMTP id 5DA7329640
        for <anders.norrbringtestdomain.se>; Mon, 28 Jan 2008 02:32:25 -0500 (EST)
Received: (qmail 85406 invoked by uid 60001); 28 Jan 2008 07:32:24 -0000

The original recipient here is 'anders.norrbringtestdomain.se' and the
mail-forward sends it to 'mailpoolnorrbring.se'.

The challenge is to poll the 'mailpoolnorrbring.se' for all mail, and
then have my local system sort everything out.

Can it be done? If so, how can I do it?

Anders.
