If you need to send out email messages through an email address with your personal domain name, you have to make sure that the provider will give you usage of their SMTP server. The aforementioned is the software system enabling e-mail messages to be dispatched. SMTP is an acronym for Simple Mail Transfer Protocol and it addresses all outgoing emails from programs, webmail and contact forms. When a message is sent out, the SMTP server confirms with all the DNS servers around the world where the emails for the receiving domain are taken care of and as soon as it obtains this info, it connects into the remote POP/IMAP server to see if the recipient mailbox is out there. When it does, the SMTP server transmits the message body and then the receiving server sends it to the mail box in which the recipient can open it up and read it. Without an SMTP server on your end, you will not be able to mail out e-mails at all.
