If you want to send e-mail messages using an email address with your very own domain, make sure that the provider will give you access to their SMTP server. The aforementioned is the software enabling email messages to be dispatched. SMTP is an abbreviation for Simple Mail Transfer Protocol and it addresses all outbound emails from applications, webmail and contact web forms. Every time a message is sent, the SMTP server checks with all the DNS servers throughout the world where the e-mails for the receiving domain name are taken care of and once it acquires this data, it will connect to the remote POP/IMAP server to see if the recipient mail box is out there. When it does, the SMTP server transmits the message body and so the receiving server sends it to the mail box in which the recipient can open it and read it. Without having a SMTP server on your end, you won't be allowed to send out e-mails in any way.
