If you would like to send out email messages through 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 that allows email messages to be dispatched. SMTP is an abbreviation for Simple Mail Transfer Protocol and it deals with all outgoing e-mails from applications, webmail and contact web forms. Every time a message is sent out, the SMTP server checks with all the DNS servers globally where the emails for the receiving domain name are managed and once it acquires this information, it will connect to the remote POP/IMAP server to find out if the recipient mail box is available. If it does, the SMTP server directs the e-mail body and the receiving server sends it to the mailbox where the recipient can open it and read it. Without an SMTP server on your end, you won't be able to mail out messages in any way.
