DNS Records, Hostnames & IP Addresses
Cisco Secure Email Cloud Gateway
For a customer allocation using Cisco Secure Email Cloud Gateway, we build the DNS records and associated hostnames as follows:
esa.<alloc>(.<region>).iphmx.com
- “esa” will list all IP Addresses for the allocation
mx1.<alloc>(.<region>).iphmx.com
- “mx1” will list all IP Addresses used in the MX Records
ob1.<alloc>(.<region>).iphmx.com
- “ob1” will list all IP Addresses used by the Hosted Interface, if any
By removing the results provided in “mx1” and “ob1”, you will have the Outgoing (NAT) IP Addresses.

Using the Dig web interface, let's take a look at an example.
