External MailServer

[mmgenius]

Hello,

Our servers have lots of mails to check (most of them are spam) and the server performance is very slow because of this. Is it possible to set-up an external mailserver who is the DNS MX-server, checks the mail and send it to the right server? If it is possible, has anyone a how-to? Can we implement this in DirectAdmin?

We are using Fedora, exim and directadmin

Kind regards
Maarten

Indeed this is the thing I need, but from the "client" side I know how I can do it. But it is how I need to setup the external server itself.

I found this in the exim.conf manual:

smart_route:
driver = manualroute
transport = remote_smtp
route_list = !+local_domains smarthost.ref.example

If I make a list forexamples server1_domains and server2_domains and I change my exim.conf file to (insert this before my local delivery):

smart_route:
driver = manualroute
transport = remote_smtp
route_list = +server1_domains "server1_ip"

smart_route:
driver = manualroute
transport = remote_smtp
route_list = +server2_domains "server2_ip"

Then I think this should work? Can anyone confirm this, or do I need to do it on another way.
