  Simple Mail Transfer Protocol
  SMTP
  
     <messaging> (SMTP) A protocol defined in STD 10, RFC
     821, used to transfer electronic mail between computers,
     usually over Ethernet.  It is a server to server protocol,
     so other protocols are used to access the messages.  The SMTP
     dialog usually happens in the background under the control of
     the message transfer agent, e.g. sendmail but it is
     possible to interact with an SMTP server using telnet to
     connect to the normal SMTP port, 25.  E.g.
  
     	telnet mhs-relay.ac.uk 25
  
     You should normally start by identifying the local host:
  
     	HELO wombat.doc.ic.ac.uk
  
     You can then issue commands to verify an address or expand an
     alias:
  
     	VRFY fred@doc.ic.ac.uk
     	VRFY postmaster
  
     or expand a mailing list:
  
     	EXPN c-help
  
     You can even send a message:
  
     	MAIL From:<fred@doc.ic.ac.uk>
     	RCPT To:<fred@mailway.doc.ic.ac.uk>
     	DATA
     	What is the point?
     	.
     	QUIT
  
     This is useful if you want to find out exactly what is
     happening to your message at a certain point.
  
     See also Post Office Protocol, RFC 822, sendmail.
