If you want to send email messages using an email address with your own domain name, make sure that the provider will give you access to their SMTP server. The aforementioned is the software which enables e-mail messages to be sent out. SMTP is an abbreviation for Simple Mail Transfer Protocol and it handles all outbound e-mails from applications, webmail and contact forms. Every time a message is sent, the SMTP server confirms with the DNS servers throughout the world where the e-mails for the receiving domain name are handled and as soon as it gets this information, it creates a connection to the remote POP/IMAP server to see if the recipient mailbox exists. When it does, the SMTP server delivers the email body and so the receiving server sends it to the mailbox in which the recipient can open it and see it. With no SMTP server on your end, you will not be allowed to mail out messages in any way.
