If you would like to send out e-mails using an e-mail address with your personal domain name, make sure that the company will give you access to their SMTP server. The aforementioned is the software system which allows email messages to be dispatched. SMTP is an acronym for Simple Mail Transfer Protocol and it handles all outgoing emails from applications, webmail and contact web forms. When a message is sent out, the SMTP server confirms with all of the DNS servers around the world where the emails for the receiving domain name are handled and once it obtains this info, it will connect to the remote POP/IMAP server to see if the recipient mail box exists. If it does, the SMTP server sends the email body and the receiving server sends it to the mailbox in which the recipient can open it and read it. With no SMTP server on your end, you won't be capable to send emails in any way.
