I tried to set up google apps in windows server 2008. Consequently I defined on Start->Administration Tools->DNS -> Forward Lookup Zones the following MX records:
Priority Mail server 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 30 ASPMX4.GOOGLEMAIL.COM 30 ASPMX5.GOOGLEMAIL.COM
I tested the proposed configuration by sending an email to the email I created but I´m receiving an
Undelivered mail returned to sender response.
The domain is fully working when accessed from a browser.
