Hi baton4eg,
I apologize for the delay in responding. There’s no way to do this through the point-and-click admin interface. To accomplish this, you would need to be comfortable writing some PHP code and creating a small addon plugin.
If you’re not comfortable with that, I’d suggest setting up an email forwarding account. Most hosts will support email forwarding, so you could set up a dummy email address, like [email protected], then have that email address automatically forward all incoming emails to the two addresses. You may not even need a dummy email address. Gmail, for instance, will allow you to automatically forward incoming emails with a specific subject.
Thank you for help, great plugin 🙂
