If you would like to send e-mail messages using an e-mail address with your very own domain name, make sure that the provider will provide you with usage of their SMTP server. The aforementioned is the software system allowing emails to be sent. SMTP is an abbreviation for Simple Mail Transfer Protocol and it handles all outgoing e-mails from programs, webmail and contact forms. Whenever a message is sent out, the SMTP server checks with the DNS servers around the world where the e-mails for the receiving domain are managed and when it acquires this info, it creates a connection into the remote POP/IMAP server to find out if the recipient mail box is available. If it does, the SMTP server directs the email body and so the receiving server sends it to the mailbox where the recipient can open it and see it. With no SMTP server on your server, you will not be able to send out emails in any way.
