            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.

       helo            = "HELO" SP Domain CRLF
