Doesn't sound too difficult @schutzy101? What you want to make sure of though is that any emails that go to the old domain get pushed to your new mailbox. Inevitably there will be emails that still get sent to old addresses and you want to make sure you get those even if you just push the entire old domain to a catchall account on the new domain.
What are you currently using for your email client @schutzy101? You should be able to add email addresses for the new domain as you did initially and but make sure the emails from the old domain have somewhere to go. I hope that helps?
