In order for you to send out email messages through an email address with your very own domain name, make sure that the company will provide you with access to their SMTP server. The aforementioned is the software system which allows emails to be dispatched. SMTP is an abbreviation for Simple Mail Transfer Protocol and it manages all outbound e-mails from programs, webmail and contact forms. Every time a message is sent, the SMTP server confirms with the DNS servers throughout the world where the e-mails for the receiving domain are handled and when it acquires this data, it creates a connection into the remote POP/IMAP server to check if the recipient mail box exists. In case it does, the SMTP server directs the email body and the receiving server sends it to the mail box in which the recipient can open it up and read it. With no SMTP server on your server, you will not be able to send out emails in any way.
