Send an email to online@openerp.com with information about your domain. For now on, they do these operation on demand, manually. We plan to develop a control center for domain management but it's not done yet. You have to send an email to ask the support team to do it.

Information you must provide:

• Do you use this domain for other services (like emails) or is it fully dedicated to your website
• Name of your instance

Extra tip: And make sure to compose a new email when emailing online@openerp.com or to reply to one of it's emails. Do not forward an existing Odoo email to this email address (like a forum email). You will receive an email confirmation with a ticket number if the Online team receives your email.
