If you'd like to send out e-mail messages through an email address with your very own domain name, make sure that the provider will provide you with access to their SMTP server. The aforementioned is the software system which permits emails to be sent. SMTP is an acronym for Simple Mail Transfer Protocol and it handles all outbound emails from apps, webmail and contact web forms. Whenever a message is sent out, the SMTP server checks with the DNS servers worldwide where the e-mails for the receiving domain name are managed and as soon as it obtains this data, it connects to the remote POP/IMAP server to check 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 mail box in which the recipient can open it and read it. Without an SMTP server on your end, you won't be capable to send out messages at all.
