If you would like to send emails using an email address with your own domain, make sure that the provider will provide you with usage of their SMTP server. The aforementioned is the software which allows e-mail messages to be dispatched. SMTP is an acronym for Simple Mail Transfer Protocol and it handles all outgoing emails from applications, webmail and contact forms. Every time a message is sent out, the SMTP server checks with all the DNS servers worldwide where the e-mails for the receiving domain are managed and once it acquires this data, it creates a connection into the remote POP/IMAP server to see if the recipient mail box is available. When it does, the SMTP server transmits the email body and then the receiving server sends it to the mail box in which the recipient can open it and read it. Without having a SMTP server on your end, you won't be able to send emails in any way.
