Does anyone know how to send mail from a domain to that domain if the domain's mail server is different than the Web host? I apologize if this isn't clear, but our client has an MX record that points to a different server than their Web host. When I use PHP's mail() function, mail is successfully sent to everyone except people within the company. How would I send mail to them?
