If you need to send emails through an email address with your own domain, make sure that the company will give you access to their SMTP server. The aforementioned is the software which enables email messages to be sent. SMTP is an acronym for Simple Mail Transfer Protocol and it deals with all outgoing email messages from applications, webmail and contact forms. When a message is sent out, the SMTP server checks with the DNS servers around the world where the e-mails for the receiving domain name are taken care of and when it gets this information, it connects to the remote POP/IMAP server to check if the recipient mail box is available. In case it does, the SMTP server transmits the e-mail body and then the receiving server delivers it to the mail box where the recipient can open it up and read it. Without an SMTP server on your server, you will not be allowed to send out emails at all.
