How to put 3rd Party Spamfilter in front of Plesk

[spiekeys]

Hello List,

by default the mx record of a custom domain points to mail.customer.com.
We also have a very good commercial spamfilter system running.

I can change the MX to nospam.customer.com, however the plesk host will still accept mails for that domain if they are delivered directly.
Is there a way to tell plesk to only accept Mails for a specific domain from a specific host?

Or how else could i put a 3rd party spam filter in front of plesk for only some specific domains?

Will the MTA listen on all interfaces for E-mails?

Or could i set up a extra customer with a extra IP and bind the MTA there? (so i could filter it with iptables)

Thanks a lot,
Mario

There are some examples there for postfix and qmail

You have to change the hostnames to your commercial spamfilter solution hostnames. I think
the company who provides this for you can help you with that.

smtpd_client_restrictions = hash:/etc/postfix/access, permit_mynetworks, reject

So you are saying i can edit the postfix config without breaking plesk or that plesk will over write it again?!
