//edit I received a reply to this question on another forum that said Any feedback on this suggestion? Also since I've got the other clients tlds (net|org, etc) parked on the account, would I delete and move these as well? //endedit On a particular VPS I have a Joomla! install. I have a client that is using their own name servers and not mine; so in cPanel I deleted the DNS for this client and the site resolves fine. I'm trying to understand how Site > Global Configuration > Mail Settings would work if the option is set to 'SMTP Server' and the client entered their mail server User Name - Password - and Host info How would the mail leave my VPS and be routed to their mail server? Since the DNS has been deleted, no MX records exist for this client on my VPS. This would pertain to user registration (Admin approval is required) lost passwords or even using the 'Mass Mail' feature of J! TIA
