Just to keep this out of the Y! realm, GApps also does this for Domain alias. example.com : primary domain example.net : alias domain FROM header : [email protected] MAIL-FROM envelope: [email protected] DKIM domain : example.net Makes some sense to be this way but DMARC will always fail for example.net.
