I have a domain kymoradio.com and initially I had created an alias domain of classickymo.com so I could have all of my emails that go to either user@kymoradio.com or user@classickymo.com go to the same mailbox. I have converted the alias domain classickymo.com to a subserver which has all of its own “stuff” because I wanted to put my website there. I would like to know if there is a way to still alias all of my kymoradio.com parten domain emails to the classickymo.com domain without having to recreate all of them in the subdomain and forward their emails to the parent kymoradio.com domain.

Thanks!

Is duplication of the users, set to not deliver mail and forward to parent account the only way anyone knows as how to accomplish my goal?
