Correct MX records to use for Google Apps?

  • 772

Ive just migrated quite a few sites to new server. In doing this i also have done a audit of the DNS setup of all our domains.

Several domains use Google Apps for their email and i noticed a couple of discrepancies in the MX records they used (please see full list of MX records below). Domain L, starts with 0 - APSMX, where as the others start with 10 - ASPMX. Non of them are identical after the first record either.

Are any of these right / wrong ?

Could there be an issue with mail not getting through due to the way they are configured ?

Domain L

0 - ASPMX.L.GOOGLE.COM
5 - ALT1.ASPMX.L.GOOGLE.COM
5 - ALT2.ASPMX.L.GOOGLE.COM
10 - ASPMX2.GOOGLEMAIL.COM
10 - ASPMX3.GOOGLEMAIL.COM

Domain PP

10 - ASPMX.L.GOOGLE.COM
20 - ALT1.ASPMX.L.GOOGLE.COM
20 - ALT2.ASPMX.L.GOOGLE.COM
30 - ASPMX2.GOOGLEMAIL.COM
30 - ASPMX3.GOOGLEMAIL.COM

Domain P

10 - ASPMX.L.GOOGLE.COM
20 - ALT1.ASPMX.L.GOOGLE.COM
20 - ALT2.ASPMX.L.GOOGLE.COM
30 - ASPMX3.GOOGLEMAIL.COM
30 - ASPMX2.GOOGLEMAIL.COM

  1. As stated by google support the following settings should be used (or, they are recommended). aspmx.l.google.com is the main server and should have top priority (1).

    Priority    Mail Server
1           ASPMX.L.GOOGLE.COM.
5           ALT1.ASPMX.L.GOOGLE.COM.
5           ALT2.ASPMX.L.GOOGLE.COM.
10          ALT3.ASPMX.L.GOOGLE.COM.
10          ALT4.ASPMX.L.GOOGLE.COM.
