If you wish to send emails using an email 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 which permits email messages to be transmitted. SMTP is an acronym for Simple Mail Transfer Protocol and it handles all outgoing emails from applications, webmail and contact web forms. Every time a message is sent, the SMTP server checks with the DNS servers throughout the world where the e-mails for the receiving domain are taken care of and when it obtains this info, it will connect into the remote POP/IMAP server to see if the recipient mail box exists. When it does, the SMTP server delivers the e-mail body and so the receiving server sends it to the mailbox where the recipient can open it and read it. Without having a SMTP server on your server, you will not be allowed to mail out emails in any way.
