If you need to send out email messages using an e-mail address with your very own domain name, you have to make sure that the provider will give you access to their SMTP server. The aforementioned is the software system that allows e-mails to be dispatched. SMTP is an abbreviation for Simple Mail Transfer Protocol and it deals with all outgoing e-mails from programs, webmail and contact forms. When a message is sent, the SMTP server confirms with the DNS servers throughout the world where the emails for the receiving domain are handled and when it acquires this information, it creates a connection to the remote POP/IMAP server to check if the recipient mailbox is available. In case it does, the SMTP server sends the message body and then the receiving server sends it to the mailbox where the recipient can open it and read it. Without having a SMTP server on your server, you won't be capable to send messages in any way.
