OK, here’s the problem, currently I use whatever is set up in WordPress as the admin email. There are two options:
1) you make a forwarding address on your side. [email protected] that forwards to [email protected] and [email protected]. Then configure WordPress with [email protected] as your admin email.
2) I create an additional parameter for the custom admin message in which you can specify a comma separated list of email addresses, “[email protected],[email protected]”
Each option has it’s problems. If you want ALL WordPress notifications to go to both email addresses, you must do option 1. If you are only interested in having user notification messages going to both addresses then option 2 would be fine, so long as you understand that my plugin only deals with user notifications. Any other messages from WordPress would continue to go to your configured admin email.
