If you wish to send email messages through an e-mail address with your very own domain, you have to make sure that the company will give you usage of their SMTP server. The aforementioned is the software system which permits email messages to be transmitted. SMTP is an abbreviation for Simple Mail Transfer Protocol and it addresses all outbound emails from programs, webmail and contact forms. Whenever a message is sent out, the SMTP server checks with all of the DNS servers throughout the world where the e-mails for the receiving domain name are managed and when it gets this info, it connects into the remote POP/IMAP server to see if the recipient mailbox is out there. If it does, the SMTP server directs the message body while the receiving server delivers it to the mail box where the recipient can open it and see it. Without an SMTP server on your end, you won't be capable to send e-mails at all.
