Hosting multiple domains, do I need multiple reverse dns?

[tonythemediaguy]

If I'm hosting multiple domains, do I need multiple reverse entries? Or should I just change the mx records to point to zimbra.myserver.com?

Thanks,

Tony

You only need one reverse DNS to the FQDN of the mail server.

I added MX records for both the FQDN of the hosting server and the virtual host name of the hosted domain. Then an A record for the virtual host.

One of my hosted domains is eastokinc.com. You can query the DNS records of this domain to see how I did it.
