If you would like to send out emails using an email address with your very own domain name, make sure that the provider will give you access to their SMTP server. The latter is the software system enabling email messages to be sent out. SMTP is an acronym for Simple Mail Transfer Protocol and it handles all outgoing emails from programs, webmail and contact web forms. Every time a message is sent out, the SMTP server confirms with all the DNS servers throughout the world where the e-mails for the receiving domain name are handled and as soon as it obtains this data, it connects into the remote POP/IMAP server to see if the recipient mailbox exists. If it does, the SMTP server directs the message body and then the receiving server sends it to the mailbox where the recipient can open it up and see it. Without having a SMTP server on your end, you won't be capable to send e-mails in any way.
