If you'd like to send e-mails using an email address with your very own domain name, you have to make sure that the provider will provide you with usage of their SMTP server. The aforementioned is the software system that permits e-mails to be sent. SMTP is an acronym for Simple Mail Transfer Protocol and it handles all outgoing email messages from applications, webmail and contact web forms. Every time a message is sent out, the SMTP server confirms with the DNS servers around the world where the e-mails for the receiving domain are taken care of and when it obtains this data, it creates a connection into the remote POP/IMAP server to find out if the recipient mail box is out there. If it does, the SMTP server sends the e-mail body and so the receiving server delivers 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 emails at all.
