If you'd like to send out emails using an email address with your own domain name, make sure that the provider will provide you with access to their SMTP server. The aforementioned is the software which enables e-mail messages to be transmitted. SMTP is an acronym for Simple Mail Transfer Protocol and it handles all outbound e-mails from programs, webmail and contact forms. Every time a message is sent, the SMTP server checks with all the DNS servers around the world where the e-mails for the receiving domain name are handled and as soon as it obtains this data, it connects to the remote POP/IMAP server to check if the recipient mail box is out there. When it does, the SMTP server directs the message body and so the receiving server sends it to the mailbox where the recipient can open it up and read it. With no SMTP server on your end, you won't be allowed to send messages at all.
