Here are the values to use in your domain's DNS settings to configure MX records for Google Apps. Each record points to a Google mail server.

Name/Host/Alias	Time to Live (TTL*)	Record Type	Priority	Value/Answer/Destination
Blank or @	3600	MX	1	ASPMX.L.GOOGLE.COM.
Blank or @	3600	MX	5	ALT1.ASPMX.L.GOOGLE.COM.
Blank or @	3600	MX	5	ALT2.ASPMX.L.GOOGLE.COM.
Blank or @	3600	MX	10	ALT3.ASPMX.L.GOOGLE.COM.
Blank or @	3600	MX	10	ALT4.ASPMX.L.GOOGLE.COM.

Steps:

1. Log in to the cPanel administrative console.
2. From the Mail section of the page, select MX Entry.
3. In the Email Routing box, select Remote Mail Exchanger and click Change.
4. Delete any current MX records you may have for the particular domain
5. Include the MX record values shown in the MX record values table.
6. Click Add New Record.
7. To add MX records for the additional domains, repeat steps 4 to 6 for those domains. Give backup servers a lower priority than the primary email server

Be aware it may take as long as 72 hours before DNS changes are propagated, depending on the time to live (TTL) that was configured for your records. Until records have been updated worldwide, you will still receive traffic to your old server.
