If you would like to send out emails through an email address with your very own domain name, make sure that the company will give you access to their SMTP server. The aforementioned is the software system enabling e-mail messages to be transmitted. SMTP is an acronym for Simple Mail Transfer Protocol and it handles all outbound email messages from programs, webmail and contact forms. Every time a message is sent, the SMTP server checks with all of the DNS servers throughout the world where the emails for the receiving domain name are taken care of and when it obtains this data, it connects to the remote POP/IMAP server to find out if the recipient mailbox is available. If it does, the SMTP server delivers the email body and the receiving server sends it to the mailbox in which the recipient can open it up and see it. With no SMTP server on your server, you won't be capable to send out messages in any way.
