Re: Exim accepting mail from specific hosts
Configuring Exim to do this would seem like a bad idea, in that your
machine then has to accept a connection to determine if you do in fact
even want to accept the mail. Ideally you would get the MX record for
your domain pointing to your providers mail server (with perhaps a
backup MX pointing to yours. That way under normal conditions mail will
be routed through your providers mail servers unless they are down, and
if they are down it will be routed to you. This will probably require
some configuration changes on your providers servers but nothing major
(just a routing line in a config file).
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
