-+ * XCLIENT Command syntax
-+ *
-+ * An example client-server conversation is given at the end of this document.
-+ *
-+ * In SMTP server EHLO replies, the keyword associated with this extension is XCLIENT. It is followed by the names of the attributes that the XCLIENT implementation supports.
-+ *
-+ * The XCLIENT command may be sent at any time, except in the middle of a mail delivery transaction (i.e. between MAIL and DOT, or MAIL and RSET). 
-+ * The XCLIENT command may be pipelined when the server supports ESMTP command pipelining. 
-+ * To avoid triggering spamware detectors, the command should be sent at the end of a command group.
-+ *
-+ * The syntax of XCLIENT requests is described below. 
-+ * Upper case and quoted strings specify terminals, lowercase strings specify meta terminals, and SP is whitespace. 
-+ * Although command and attribute names are shown in upper case, they are in fact case insensitive.
-+ *
-+ *   xclient-command = XCLIENT 1*( SP attribute-name"="attribute-value )
-+ *
-+ *   attribute-name = ( NAME | ADDR | PORT | HELO | PROTO | LOGIN)
-+ *
-+ *   attribute-value = xtext
-+ *
-+ * Attribute values are xtext encoded as per RFC 1891.
-+ * The NAME attribute specifies an SMTP client hostname (not an SMTP client address), [UNAVAILABLE] when client hostname lookup failed due to a permanent error, or [TEMPUNAVAIL] when the lookup error condition was transient.
-+ *
-+ * The ADDR attribute specifies an SMTP client numerical IPv4 network address, an IPv6 address prefixed with IPV6:, or [UNAVAILABLE] when the address information is unavailable. Address information is not enclosed with [].
-+ *
-+ * The PORT attribute specifies the SMTP client TCP port number as a decimal number, or [UNAVAILABLE] when the information is unavailable.
-+ * The HELO attribute specifies an SMTP HELO parameter value, or the value [UNAVAILABLE] when the information is unavailable.
-+ * The PROTO attribute specifies either SMTP or ESMTP.
-+ * 
-+ * Note 1: syntactically valid NAME and HELO attribute-value elements can be up to 255 characters long. 
-+ * The client must not send XCLIENT commands that exceed the 512 character limit for SMTP commands. 
-+ * To avoid exceeding the limit the client should send the information in multiple XCLIENT commands; for example, send NAME and ADDR first, then HELO and PROTO.
-+ *
-+ * Note 2: [UNAVAILABLE], [TEMPUNAVAIL] and IPV6: may be specified in upper case, lower case or mixed case.
