[Greylist-users] multi server instance?

[Barry Murphy]

I use Exim and currently use greylistd which has worked just great for me,
the only issue is the server is getting high CPU with the addition of new
reseller clients, so I want to move the spam/virus scanning to 2 frontend
servers rather.

I wonder if anyone has a XEN image (or even a howto) for such a server
configuration, the frontend servers would also need to do a callout to the
main server to ensure the receipt actually exists. I plan on using XEN so
additional MX frontends are easy to deploy.

Cheers
Barry
