I set up gmail for use with one domain. When I go to mail.mydomain.tld to set it up I get this:
"This domain has already been registered with Google Apps. Please contact your domain administrator for instructions on using Google Apps with this domain."
I haven't set up anything other than check a box "use Gmail for this domain" on Dreamhost control panel.
How do I actually add and delete email addresses?
I don't have a user name and password set up yet, as far as I know.
