What I am attempting to do is ensure all ingress web traffic [http(s)] to
exampledomain1.com forwards to
exampledomain2.com but I still want to use the MX record of
exampledomain1.com to point to at google's mail relays for mail delivery.
I know that I can do this at the application level with redirects and a web-server but in this case I will not be able to setup a physical server for A records to resolve. Do I just create the MX and TXT records for this domain without any A records and setup URL Forwarding to the URL of the second domain? Does this setup present security issues? Without hosting a web-server to redirect at the application level is this even possible?
Ultimately, a company I'm helping would like to buy up many domains similar to their name that will redirect to one master domain that represents the brand.
