Gmail MX Record Changes

Mail servers

Here are the values to be included when you configure MX records for Google Apps with your domain host. Please note the initial numbers in the Value / Answer / Destination column show MX record priority. See understand MX records for details about adding MX records to your domain.

Priorities

The initial numbers in the Value / Answer / Destination column show the relative priorities of the Google servers. The values do not need to be exactly those shown in the table; different domain hosts have different systems for setting MX record priority. Regardless of the system,ASPMX.L.GOOGLE.COM must be the top priority record

The priority level assigned to an MX record establishes preferences when there are multiple MX records for one domain. A correct priority value assigns a preference to the primary MX record. In this fashion, backup MX records are given a lower priority.

aspmx.l.google.com. is the most important mail server, and should be assigned a unique priority.

If your DNS provider allows you to assign numbers to MX records, choose the lowest number foraspmx.l.google.com., and assign higher numbers to the back-up servers. In terms of priority values, the lowest number gets the highest priority.

If your DNS provider doesn’t use numbers to assign priorities, choose the highest priority setting, or designate aspmx.l.google.com. as the primary server.

And if your DNS provider allows only one server, or doesn’t allow ranking, simply enteraspmx.l.google.com. as the only record.
