If you would like to send out email messages through an e-mail address with your personal domain, make sure that the company will provide you with usage of their SMTP server. The aforementioned is the software that enables emails to be transmitted. SMTP is an abbreviation for Simple Mail Transfer Protocol and it addresses all outbound emails from applications, webmail and contact forms. Whenever a message is sent out, the SMTP server confirms with the DNS servers throughout the world where the e-mails for the receiving domain name are taken care of and when it gets this information, it creates a connection into the remote POP/IMAP server to check if the recipient mailbox is available. When it does, the SMTP server transmits the e-mail body and the receiving server delivers it to the mail box where the recipient can open it and see it. With no SMTP server on your server, you won't be able to send messages at all.
