Its part of the xtables-addon package in the ASL kernels, for non-ASL kernels we could probably do a few hundred thousand the old way without much impact.
Hi Scott,

How can we go about implimenting this solution?

Hi Scott,

Ok got PG serevr up and running.
Had a ton of issues with with Clamav permissions but it seems to working now.

I have copied /var/qmail/control/rcpthosts from the PSA server to the PG server
On the PG server /var/qmail/control/smtproutes I added :mymailserver.co.za

On my local PSA server i set up two domains with a MX 5 to the PG server

On the PG server i can see mail coming in.
On the PG server i dont see any SPAMASSASSIN notice messages or logs.
On the PG server i dont see any Clam email scanning in the logs.

Any suggestion or pointer will be great!
