I would like to send email from an address I control, but currently this means that I have to create a Google Account for it and then add it as a developer. Given that the domain is hosted on Google Apps, there’s already an address like that, aliased to me. Google won’t let me create a new account with that email, so I’m stuck.
Is there a simple way to prove I own the address and send mail from it, or am I out of luck?
The From address needs to be registered as an admin of the application (or the address of the logged-in user, which obviously doesn’t apply here).
