Charter for Working Group

The SMTP Extensions Working Group is chartered to develop extensions to
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
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.
