If you'd like to send email messages using an email address with your domain name, make sure that the company will give you access to their SMTP server. The aforementioned is the software enabling e-mail messages to be transmitted. SMTP is an acronym for Simple Mail Transfer Protocol and it manages all outgoing e-mails from applications, webmail and contact forms. Every time a message is sent, the SMTP server checks with all of the DNS servers throughout the world where the e-mails for the receiving domain are handled and as soon as it gets this data, it creates a connection to the remote POP/IMAP server to check if the recipient mailbox is out there. If it does, the SMTP server directs the email body and so the receiving server delivers it to the mail box where the recipient can open it up and read it. With no SMTP server on your server, you won't be allowed to send out emails at all.
