SMTP is an abbreviation that stands for Simple Mail Transfer Protocol. This protocol allows applications to transmit email messages over the Internet. Basically, SMTP handles your outgoing mail. Your email application connects to your mail server via SMTP and sends the messages. Receiving emails, however, utilises two other different protocols - POP3 or IMAP.
In order to prevent spam from being sent via our mail servers, we require SMTP authentication. This means that you have to enter your full email address as username and your email account password if you want to use our email server to send messages.
