HI All

After a long testing now i want to go live of my email server. I need some guideline.

I have two domains which i need to change MX record from hosting to my IP.
Example 1.raj.com

Now i have one public IP like 122.xxx.xxx.xxx, when i change MX record can i give that same public IP for both domains for resolve for domains.

Internally i install Zimbra with both Domains working fine now i need to send mails to out side and receive. Even i need to NAT in the router.

With regards
