Mailserver, IP Range

[exiof]

How do i limit the hosts which can send to a specific domain, my probleme is that a spammer delivers directly to my mailserver, and i have a Relay server which handles Spam / Virusscanning for 2 domains on my plesk.. The probleme is that i really want all the other mail going in, but for those 2 domains i only want mail to come from 2 specific IP addresses

I don't know any easy and straight setup for this in qmail but, you can do this easily with smtp plugin. For an idea of how to write this, check out
the qmail plugin site
