Techout592 the E-mail of your primary account uses your own domain. You can change the E-Mail address of your primary account by logging into your second account which I've made admin, going to the profile page of your mail account, clicking on "Edit" and setting the E-Mail address to a different one. If you have just 1 GMail address for example, you could set your second's account E-Mail to something random (non-existing, as you don't need it ATM) and setting your primary's account address to your GMail address (just so that there are not 2 same E-Mail addresses). I hope that you understand what I mean
Edit: FreeFlarum also received an automatic reply E-mail originating from your E-mail, but it was sent into spam, which makes me think that there is something wrong with your mail server more now. You should check its settings
