    Status of this document
    -----------------------

      This document is a Fidonet Standards Proposal (FSP).

      This document specifies an optional Fidonet standard protocol for
      the Fidonet community, and requests discussion and suggestions for
      improvements.

      This document is released to the public domain, and may be used,
      copied or modified for any purpose whatever.

    Abstract
    --------

      Private messages within FidoNet only have one recipient address.
      Multiple copies of the same message have to be sent to a FidoNet-
      to-Internet gateway in order to address multiple recipients. This is
      a proposal to indicate the addresses of multiple recipients in the
      body of the message sent to the gateway.

    1. Scope
    --------

      This standard is specified for FTN netmail messages sent to a
      FidoNet-to-Internet gateway. Users are able to add this information
      manually, although message editors could support this and make it
      transparent to the user.

    2. Background
    -------------

      Three types of recipient addresses can be specified on the Internet
      and are reflected in this suggestion: To, Cc and Bcc. "To" are the
      primary recipient(s) of the message. "Cc" is short for Carbon Copy
      and lists the recipients that are intended to receive the message as
      "informational". The last option "Bcc" is short for Blind Carbon
      Copy. Recipients lists as Bcc recipients will not show up in the
      headers of the Internet message, but get a copy anyway.

    3. Format
    ---------

      Immediately following the kludge lines, one or more of the following
      lines can be inserted in the message. If a To: line is present, then
      these lines follow the To: line.

      GW-To: <e-mail address>[,<e-mail address>[...]]
      GW-Cc: <e-mail address>[,<e-mail address>[...]]
      GW-Bcc: <e-mail address>[,<e-mail address>[...]]

      Where <e-mail address> is in the form of

         ramon@wsd.wline.se
      or
         wsd.wline.se!ramon

      Multiple addresses can be specified on the same line, separated by a
      comma with optionally spaces around the comma. There is no limit
      regarding the length of the line. The line must be terminated by a
      single carriage return.

      The GW-To: line replaces the To: lines.

      The reason for GW-Cc is that "Cc:" by itself is expanded by some
      editors and used to generate multiple copies of a message.

    4. Implementation notes for gateways
    ------------------------------------

      Gateways supporting this format add the e-mail addresses mentioned
      in any of these three headers to the envelope file and create on
      outbound (probably UUCP or SMTP) body text message. Rules for the
      maximum length of envelope files (if any) apply.

      The headers section of the RFC822 message will list the e-mail
      addresses under the To: and Cc: headers. A Bcc: header must not be
      added!
