Description of Working Group:































The SMTP Extensions Working Group is chartered to develop extensions to 































the































base SMTP protocol (RFC821) to facilitate the more efficient 































transmission of 8































bit text and binary data.  Among the extensions to be considered to SMTP 































are the































elimination of the ASCII text character restriction and line length 































restriction































to allow the sending of arbitrary 8 bit character sets, and the 































definition of































mechanisms to facilitate binary transmission, and extensions to the































negotiation sequence to facilitate batch transmission.
