        (4)   (Line Breaks) A line break in a text body, represented

                    represented by a (RFC 822) line break, which is also a
                    CRLF sequence, in the Quoted-Printable encoding.  Since
                    the canonical representation of media types other than
                    text do not generally include the representation of
                    line breaks as CRLF sequences, no hard line breaks
                    (i.e. line breaks that are intended to be meaningful
                    and to be displayed to the user) can occur in the
                    quoted-printable encoding of such types.  Sequences
                    like "=0D", "=0A", "=0A=0D" and "=0D=0A" will routinely
                    appear in non-text data represented in quoted-
                    printable, of course.

                    Note that many implementations may elect to encode the
                    local representation of various content types directly
                    rather than converting to canonical form first,
                    encoding, and then converting back to local
                    representation.  In particular, this may apply to plain
                    text material on systems that use newline conventions
                    other than a CRLF terminator sequence.  Such an
                    implementation optimization is permissible, but only
                    when the combined canonicalization-encoding step is
                    equivalent to performing the three steps separately.

                    programs which transport messages from one user to
                    another, or perform a portion of such transfers) are
                    known to pad lines of text with SPACEs, and others are
                    known to remove "white space" characters from the end
                    of a line.  Therefore, when decoding a Quoted-Printable
                    body, any trailing white space on a line must be
                    deleted, as it will necessarily have been added by
                    intermediate transport agents.

        (4)   (Line Breaks) A line break in a text body, represented

                    represented by a (RFC 822) line break, which is also a
                    CRLF sequence, in the Quoted-Printable encoding.  Since
                    the canonical representation of media types other than
                    text do not generally include the representation of
                    line breaks as CRLF sequences, no hard line breaks
                    (i.e. line breaks that are intended to be meaningful
                    and to be displayed to the user) can occur in the
                    quoted-printable encoding of such types.  Sequences
                    like "=0D", "=0A", "=0A=0D" and "=0D=0A" will routinely
                    appear in non-text data represented in quoted-
                    printable, of course.

                    Note that many implementations may elect to encode the
                    local representation of various content types directly
                    rather than converting to canonical form first,
                    encoding, and then converting back to local
                    representation.  In particular, this may apply to plain
                    text material on systems that use newline conventions
                    other than a CRLF terminator sequence.  Such an
                    implementation optimization is permissible, but only
                    when the combined canonicalization-encoding step is
                    equivalent to performing the three steps separately.

        RFC 2047 provides support for non-US-ASCII character sets in RFC 822
        message header comments, phrases, and any unstructured text field.
        This is done by defining an encoded word construct which can appear
        in any of these places.  Given that these are fields intended for
        display, it is sometimes necessary to associate language information
        with encoded words as well as just the character set.  This
        specification extends the definition of an encoded word to allow the
        inclusion of such information.  This is simply done by suffixing the
        character set specification with an asterisk followed by the language
        tag.  For example:

                    From: =?US-ASCII*EN?Q?Keith_Moore?= <moore@cs.utk.edu>

        RFC 2047 provides support for non-US-ASCII character sets in RFC 822

        This is done by defining an encoded word construct which can appear

        inclusion of such information.  This is simply done by suffixing the
        character set specification with an asterisk followed by the language
        tag.  For example:

            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").

       -- RFC 2281, 4.1.1.1.

     The second step in the procedure is the RCPT command.

            RCPT TO:<forward-path> [ SP <rcpt-parameters> ] <CRLF>

     The first or only argument to this command includes a forward-path
     (normally a mailbox and domain, always surrounded by "<" and ">"
     brackets) identifying one recipient.  If accepted, the SMTP server
     returns a 250 OK reply and stores the forward-path.  If the recipient
     is known not to be a deliverable address, the SMTP server returns a
     550 reply, typically with a string such as "no such user - " and the
     mailbox name (other circumstances and reply codes are possible).
     This step of the procedure can be repeated any number of times.

        -- RFC 2821, 4.1.1.3.

        This command is used to identify an individual recipient of the mail
        data; multiple recipients are specified by multiple use of this
        command.  The argument field contains a forward-path and may contain
        optional parameters.

        The forward-path normally consists of the required destination
        mailbox.  Sending systems SHOULD not generate the optional list of
        hosts known as a source route.

        /* -- RFC 2821, 7.2.

     Addresses that do not appear in the message headers may appear in the
     RCPT commands to an SMTP server for a number of reasons.  The two
     most common involve the use of a mailing address as a "list exploder"
     (a single address that resolves into multiple addresses) and the
     appearance of "blind copies".  Especially when more than one RCPT
     command is present, and in order to avoid defeating some of the
     purpose of these mechanisms, SMTP clients and servers SHOULD NOT copy
     the full set of RCPT command arguments into the headers, either as
     part of trace headers or as informational or private-extension
     headers.  Since this rule is often violated in practice, and cannot
     be enforced, sending SMTP systems that are aware of "bcc" use MAY
     find it helpful to send each blind copy as a separate message
     transaction containing only a single RCPT command.

            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").

       -- RFC 2281, 4.1.1.1.
