If you'd like to send emails using an email address with your own domain, make sure that the provider will provide you with access to their SMTP server. The aforementioned is the software system which permits e-mail messages to be transmitted. SMTP is an acronym for Simple Mail Transfer Protocol and it deals with all outgoing emails from apps, webmail and contact forms. Every time a message is sent, the SMTP server confirms with the DNS servers throughout the world where the emails for the receiving domain name are handled and as soon as it acquires this information, it creates a connection to the remote POP/IMAP server to find out if the recipient mailbox exists. In case it does, the SMTP server transmits the message body and the receiving server sends it to the mailbox in which the recipient can open it and read it. With no SMTP server on your server, you won't be allowed to send emails at all.
