The other option would be to firewall off port 25 for inbound traffic unless it came from your providers mail server, although this is much less elegant

Hi,
I've implemented a spam service where a provider is filtering all my domain's mail before it hits my server. I want to lock down my mail server so it only accepts mail from those machines to prevent spammers from mailing directly to my host and doing directory harvests.
What do I need to stick in my exim.conf to accept mail from just those hosts that will be processing my mail?
thanks, Adam
