If you wish to send e-mails using an e-mail address with your very own domain, make sure that the company will provide you with access to their SMTP server. The aforementioned is the software which enables e-mail messages to be dispatched. SMTP is an abbreviation for Simple Mail Transfer Protocol and it manages all outbound email messages from programs, webmail and contact forms. When a message is sent out, the SMTP server confirms with all the DNS servers worldwide where the emails for the receiving domain are taken care of and when it obtains this information, it creates a connection to the remote POP/IMAP server to see if the recipient mailbox is available. When it does, the SMTP server transmits the e-mail body while the receiving server sends it to the mail box in which the recipient can open it and see it. With no SMTP server on your end, you won't be able to send e-mails in any way.
