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

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.
