Hello,
I want to realize the following setup in DNS for the domain test.com test.com. IN MX 5 mx1.test.com. test.com. IN MX 10 mx2.test.com. test.com. IN MX 15 mx3.test.com.
Can I force all incoming mail for test.com to deliver first to mx2 or mx3?
Solution 1: Setup iptables on mx1 to only receive mail from mx2 and mx3.
Solution 2: Different DNS-entries for internal or external use.
But I think there should be a better solution for this. Does someone have a better setup for this?
I want this setup, because the load for virus-scanning should go away from mx1 to mx2 and mx3. But the mail should be delivered (through mx2 or mx3) to mx1 because mx1 has the best internet-connection for my clients to check the mail per pop3, imap, ....
I want to use standard setup with qmail, qmail-scanner, vpopmail for this.
Thanks,
Walter
