If you would like to send out emails through an e-mail address with your very own domain name, you have to make sure that the provider will provide you with usage of their SMTP server. The aforementioned is the software system that permits e-mail messages to be transmitted. SMTP is an abbreviation for Simple Mail Transfer Protocol and it deals with all outbound emails from programs, webmail and contact web forms. When a message is sent, the SMTP server checks with all the DNS servers worldwide where the emails for the receiving domain are taken care of and once it gets this information, it connects to the remote POP/IMAP server to check if the recipient mailbox is available. In case it does, the SMTP server sends the email body and then the receiving server sends it to the mail box where the recipient can open it and read it. With no SMTP server on your end, you will not be capable to send out e-mails in any way.
