/* -- RFC 2821, 3.2.
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").
