              3.2 Client Initiation
  
           Once the server has sent the welcoming message and the client has
           received it, the client normally sends the EHLO command to the
           server, indicating the client's identity.  In addition to opening the
           session, use of EHLO indicates that the client is able to process
           service extensions and requests that the server provide a list of the
           extensions it supports.  Older SMTP systems which are unable to
           support service extensions and contemporary clients which do not
           require service extensions in the mail session being initiated, MAY
           use HELO instead of EHLO.  Servers MUST NOT return the extended
           EHLO-style response to a HELO command.  For a particular connection
           attempt, if the server returns a "command not recognized" response to
           EHLO, the client SHOULD be able to fall back and send HELO.
  
           In the EHLO command the host sending the command identifies itself;
           the command may be interpreted as saying "Hello, I am <domain>" (and,
           in the case of EHLO, "and I support service extension requests").
  
         -- RFC 2281, 4.1.1.1.
  
         ehlo            = "EHLO" SP Domain CRLF
