I have added several wildcard MX records on my Domain Management Console, which all point to Google Email server and their backup email servers, e.g.
10 *.mydomain.net ASPMX.L.GOOGLE.COM 3600 20 *.mydomain.net ALT1.ASPMX.L.GOOGLE.COM 3600 20 *.mydomain.net ALT2.ASPMX.L.GOOGLE.COM 3600 30 *.mydomain.net ASPMX2.GOOGLEMAIL.COM 3600 30 *.mydomain.net ASPMX3.GOOGLEMAIL.COM 3600 30 *.mydomain.net ASPMX4.GOOGLEMAIL.COM 3600 30 *.mydomain.net ASPMX5.GOOGLEMAIL.COM 3600
On the Google Apps side, I can setup domain aliases. That way, I can have two email addresses using the same account, e.g. email@example.com and firstname.lastname@example.org.
In order for the domain alias to work, I need to setup the corresponding MX records for the domain. My question: I want to cover all possible domain aliases with the above wildcard MX records, such that whenever I add a new domain alias in Google Apps, emails to the new alias should work without any additional changes on the Domain Management side. Is this setup possible?
