Different spam rules

["Fettke, Dirk" <Di...@its-technidata.de>]

Hi,

I'm looking for a solution for filter spam-mails, depending of
recipient-domains.

We have a postfix-mailrelay with amavisd and spamassassin working (but
without local mailboxes) for delivering emails to our customers
mailservers.
Each of them have different spam rules, white- and blacklists.

I searched google, but haven't find anything for use.

What have i to do, to realize these requirements?

Thanks
Dirk
