If you want to send e-mail 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 enables email messages to be sent. SMTP is an acronym for Simple Mail Transfer Protocol and it addresses all outgoing e-mails from programs, webmail and contact web forms. Every time a message is sent out, the SMTP server checks with the DNS servers worldwide where the emails for the receiving domain name are taken care of and when it acquires this info, it will connect to the remote POP/IMAP server to check if the recipient mail box exists. If it does, the SMTP server directs the email body and so the receiving server delivers it to the mail box in which the recipient can open it and read it. With no SMTP server on your end, you will not be capable to send out messages at all.
