What is SMTP Email Server ?

SMTP (Outgoing) E-mail Servers

     The ability to provide Email services to clients includes two critical functions: SMTP and POP3. Together, they provide the means for clients to send out-going mails and check for new incoming mail, respectively.
     SMTP service is the side of Email that allows clients to send out-going E-mail messages to any valid Email address. The SMTP server performs two basic but important functions. First, it verifies that anyone attempting to send outgoing E-mails through the SMTP server has the right to do so. Secondly, it sends the out-going mails and if undeliverable, sends the message back to the sender.
     You need to configure your Email client so that it knows what SMTP server to use for sending outgoing E-mail messages. In order to send mails through the proper SMTP servers, configure your e-mail client to access the SMTP (Out-going Mails) Server: yourdomain.com.
