If you need to send e-mail messages through an e-mail address with your personal domain name, make sure that the provider will provide you with access to their SMTP server. The aforementioned is the software system allowing e-mails to be dispatched. SMTP is an abbreviation for Simple Mail Transfer Protocol and it manages all outgoing email messages from programs, webmail and contact forms. Whenever a message is sent, the SMTP server checks with all of the DNS servers around the world where the emails for the receiving domain name are taken care of and once it acquires this data, it will connect to the remote POP/IMAP server to check if the recipient mailbox is out there. If it does, the SMTP server transmits the message body and so the receiving server sends it to the mailbox in which the recipient can open it and see it. Without having a SMTP server on your server, you won't be allowed to send messages at all.
