If you wish to send email messages through an e-mail address with your very own domain name, make sure that the company will give you usage of their SMTP server. The aforementioned is the software system that allows email messages to be transmitted. SMTP is an acronym for Simple Mail Transfer Protocol and it manages all outbound emails from programs, webmail and contact web forms. Every time a message is sent out, the SMTP server checks with all of the DNS servers worldwide where the emails for the receiving domain name are taken care of and when it acquires this data, it creates a connection into the remote POP/IMAP server to check if the recipient mail box is available. In case it does, the SMTP server transmits the email body while the receiving server delivers it to the mail box where the recipient can open it and read it. Without an SMTP server on your end, you won't be able to send out messages in any way.
