Mail Relaying & Routing (SMTP)

SMTP is a secure, quick and effective means of transmitting email.

SMTP is short for Simple Mail Transfer Protocol, a protocol for sending email messages between servers.

Most email systems that send mail over the Internet uses SMTP to send messages from one server to another; the messages can then be retrieved with an email client using either POP or IMAP. SMTP is also generally used to send messages from a mail client to a mail server.
