       faxmail - HylaFAX mail-to-fax gateway application

       faxmail [ options ] [ destination [ from ] ]

       faxmail takes an electronic mail message on standard input and submits
       it as a facsimile to a HylaFAX server for transmission.

       faxmail is designed for use in constructing electronic mail to
       facsimile gateway services.  For example, mail aliases may be created
       to automatically transmit electronic mail; e.g.

            sam: "|/usr/bin/faxmail sam@5551212"
       or faxmail may be used as a ``mail transport agent'', extracting the
       necessary delivery information directly from the envelope of the mail

       faxmail formats a mail message according to the following rules: First
       it parses the envelope information interpreting any meta-header
       information (see below) that is present.  Once the entire envelope has
       been collected it emits a formatted set of header lines.  By default
       all header information except the ``From'', ``To'', ``Cc'',
       ``Subject'', and ``Date'' lines are discarded.  Header lines that are
       kept have the tag (the string to the left of the ``:'') set in a bold
       font and the value (the string to the right of the ``:'') set in an
       italic font.  Mail messages that conform to the Multipurpose Internet
       Mail Extensions (MIME) specification are parsed and handled according
       to the rules given below.  Plain text body parts of a mail message are
       formatted in a text font with any long lines wrapped at word boundaries
       unless the -c option has been specified.

       By default, faxmail sets all text in 10 point type on an 8.5" by 11"
       portrait-oriented page with .35" top margin, .25" bottom margin and
       .25" left and right hand margins.  There are command-line options to
       control the point size, page dimensions, orientation, and multi-column
       formatting.  Text formatting can also be controlled through meta-header
       directives placed in the envelope of the mail message.

       faxmail pre-processes the envelope information (i.e. the header lines)
       before formatting the message contents.  Header lines whose names begin
       with ``X-FAX-'' (case-insensitive) are handled specially-they are
       treated as command directives that specify how to generate the
       resultant POSTSCRIPT or, optionally, how to deliver the resulting
       document as facsimile.  The set of known meta-headers corresponds to
       the set of configuration parameters defined below.  A meta-header is
       specified as ``X-FAX-parameter'' where parameter is the name of a
       configuration parameter; e.g.  ``X-FAX-TabStop'' to set the number of
       spaces between tab stops.

       Controls for specifying headers to be passed through in the formatted
       text identify not only which headers but also the order in which the
       headers should be emitted.  faxmail initializes the set of headers to
       retain to: ``To From Subject Cc Date''.  If this order is acceptable
       then additional headers can simply be added with the X-FAX-Headers
       directive; e.g. ``X-FAX-Headers: Message-id''.  If however a different
       order is desired then the header set should be cleared with a ``clear''
       header tag and then completely specified in the desired order; for

       X-FAX-Headers: clear Message-id Date To Subject From Cc

       will cause headers to be emitted in the order ``Message-Id Date To
       Subject From Cc'' (depending on what headers are present).  Note in
       particular that all header lines in the envelope can be suppressed by
       specifying ``X-FAX-Headers: clear''; this is useful, for example, when
       the body of the mail message contains a preformatted document that is
       to be transmitted.

       In addition to the above controls, faxmail can also be instructed to
       substitute an arbitrary string for a header tag when generating the
       final envelope.  This facility can be used to better format ad-hoc
       header information that is passed through the envelope of the message.
       The ``X-FAX-MapHeader'' meta-header specifies how to map a header line.
       For example,

       X-FAX-MapHeader: x_FAX_For Deliver FAX To

       would cause any header ``x_FAX_For'' that appeared in the envelope to
       be replaced in the formatted envelope by ``Deliver FAX To''.

       faxmail parses MIME mail messages and does some rudimentary work to:

       •  decode encoded parts,

       •  formats the message and text parts into a Postscript document

       •  insert ``digest dividers'' between multipart/digest subparts,

       •  format message/rfc822 parts as described above for the top-level
          envelope, and

       •  submit all other attached documents to be faxed.

       MIME processing is fairly simple and (currently) somewhat constrained.
       faxmail has builtin support for the following MIME parts: text/plain,
       multipart/mixed, multipart/digest, message/rfc822,
       application/postscript, and application/x-faxmail-prolog.  Parts can
       also be processed through external processing scripts that faxmail
       looks for in a ``MIME converters'' directory hierachy.  External
       scripts may override builtin processing or suppliment the builtin
       support.  For each MIME body part with type T and subtype S faxmail
       checks first for an exceutable script named T/S in the converter
       heirarchy.  If a script exists then it is run and the resulting output
       is saved as a document submitted to HylaFAX.  If the output is empty,
       the part is suppressed, and will not be submitted.  All other parts
       will be saved as documents and submitted to HylaFAX.  faxmail uses the
       typerules(5F).  mechanism to convert file formats into one of the
       format HylaFAX supports.

       The builtin handling support is as follows: text/plain parts are
       formatted using the default text font and point size; multipart/mixed
       are ``burst'' and interpreted per the specification but are otherwise
       unformatted; multipart/digest are burst and an optional ``digest
       divider'' marking may be inserted before each subpart; message/rfc822
       are formatted as described above with envelope header lines culled and
       formatted with bold and italic fonts (in addition, if there is
       insufficient space in the current output page/column for the message
       envelope, optional divider, and one line of text, then faxmail will
       insert a ``break'' so the the message starts at the top of the next
       page/column); application/postscript are copied through untouched to
       the output; application/x-faxmail-prolog are copied through untouched
       to the end of the prologue section of the generated PostScript document
       to permit customization of the formatted output.

       faxmail supports the following Content-Transfer-Encoding schemes: 7bit,
       8bit, binary, base64, quoted-printable, and x-uuencode.  Any character
       set that is not us-ascii is treated as iso-8859-1.

       When faxmail is invoked it delivers the formatted document directly to
       a HylaFAX server for transmission as facsimile.  Command line arguments
       may be supplied to specify the delivery destination and sender
       identity; typically from information extracted by the mail transport
       facility.  A command line destination is specified with the same syntax
       as the argument for the -d option to the sendfax(1) command.  Similarly
       any from identity specified on the command line follows the same rules
       as the -f option to sendfax.  An explicit dialstring to use in delivery
       can also be specified with an X-FAX-Dialstring header in the mail
       message envelope.  If no sender identity is provided on the command
       line then faxmail will extract it from the ``From'' line in the
       envelope.  faxmail will not submit a message for delivery if either the
       dialstring or sender identity is missing or null.

       X-FAX- header lines may be included in the mail message envelope to
       control the submission and delivery process.  As above these lines are
       specified as ``X-FAX-parameter'' where parameter is the name of a
       configuration parameter for the sendfax program; e.g.  ``X-FAX-VRes''
       to set the vertical resolution of the transmitted facsimile.  By
       default automatic cover page generation is enabled when direct delivery
       is used; this can be overridden with the -n option on the command line
       or by including an X-FAX-AutoCoverPage header in the message envelope.

       -1        Set text in one column (default).

       -2        Set text two columns.

       -b font   Make font, a POSTSCRIPT font name, the ``bold font'' used to
                 set header lines.  The default bold font is Helvetica-Bold.

       -c        Clip long text lines instead of wrapping them at page

       -C cover  Use the cover page template file specified by cover.

       -f font   Make font, a POSTSCRIPT font name, the text font used to set
                 the body of mail messages.  The default text font is Courier.

       -H height Use height as the height, in inches, of the output page.  The
                 default page height is taken from the default page size.

       -i font   Make font, a POSTSCRIPT font name, the ``italic font'' used
                 to set header lines.  The default italic font is Helvetica-

                 Set the page margins; the default margins are: left and right
                 .25 inch, top .35 inch, bottom .25 inch.

       -n        Suppress auto cover page generation.

       -N        Suppress formatting of mail envelope headers.

       -p size   Set all text using size for the font point size.

       -r        Set pages rotated by 90 degrees (in ``Landscape mode'').

       -R        Set pages unrotated (in ``Portrait mode'').

       -s size   Set the page size to use.  Cover pages are normally generated
                 using a system-default page size (usually letter-size pages,
                 8.5" by 11", for sites in North America).  Alternate page
                 sizes are specified symbolically using either the name or
                 abbreviation of an entry in the pagesizes(5F) database; e.g.
                 a3 (ISO A3), a4 (ISO A4), a5 (ISO A5), a6 (ISO A6), b4 (ISO
                 B4), na-let (North American Letter), us-leg (American Legal),
                 us-led (American Ledger), us-exe (American Executive), jp-let
                 (Japanese Letter), and jp-leg (Japanese Legal).  Comparisons
                 are case-insensitive and any match of a substring of the full
                 page-size name is sufficient; e.g. ``legal'' would match
                 ``American Legal''.

       -t notify Specify the notify value to use

       -T        Trim leading blank lines from text parts.  If the text part
                 is completely empty, it will effectively be skipped.

       -u user   Set the user name to use when logging in to do direct
                 delivery.  By default the user is specified by the MailUser
                 configuration parameter (see below).  If a null user name is
                 specified, then the facsimile will be submitted using the
                 identity of the user that invoked faxmail.

       -v        Enable tracing of envelope, MIME, and job submission
                 processing.  Diagnostic information is written to the
                 standard error (envelope and MIME processing) and standard
                 output (job submission).

       -W width  Use width as the width, in inches, of the output page.  The
                 default page width is taken from the default page size.

       faxmail reads configuration information from the files
       /usr/lib/fax/hyla.conf, /usr/lib/fax/sendmail.conf,
       /usr/lib/fax/faxmail.conf, and ~/.hylarc; in that order.  Configuration
       files follow the conventions described in hylafax-client(1).  In
       addition to the formatting configuration parameters below, all of the
       parameters listed in the sendfax(1) man page apply as well.

       The following configuration parameters are recognized to support

       Values marked as inches are specified using a syntax that identifies
       one of several possible units:
              #.##bp    big point (1in = 72bp)
              #.##cc    cicero (1cc = 12dd)
              #.##cm    centimeter
              #.##dd    didot point (1157dd = 1238pt)
              #.##in    inch
              #.##mm    millimeter (10mm = 1cm)
              #.##pc    pica (1pc = 12pt)
              #.##pt    point (72.27pt = 1in)
              #.##sp    scaled point (65536sp = 1pt)

       Unit names can be upper or lower case but no white space is permitted
       between the number and the unit.  Values specified with no unit are
       interpreted as points.

       The configuration parameters are explained below.  Most parameters
       correspond to a command line option.  Parameter values identified above
       as inches are converted according to the conventions described above.

       AutoCoverPage  Control whether or not a cover page is automatically
                      generated for each job.

       BoldFont       The name of the font to use to set header tags (i.e. the
                      string to the left of the ``:'').

       Columns        The number of columns to set text in.  (Equivalent to
                      the -m option.)

       DigestDivider  The string to emit in the output before each subpart of
                      a multipart/digest mail message.  This string is
                      typically a POSTSCRIPT procedure that draws a mark of
                      some sort.  Dividers are expected to use no more
                      vertical space on the output page than a line of text.

       FontPath       The path where Adobe Font Metric (AFM) files are
                      located; by default /usr/share/ghostscript/fonts.

       GaudyHeaders   Control whether or not to use a gaudy-style page header.
                      Enabling gaudy headers implicitly enables page headers.

       Headers        Define the headers retained from the envelope and
                      specify the order that they should be emitted in the
                      formatted output.  The set of headers is initialized to
                      ``To From Subject Cc Date''.  Headers specified are
                      appended to this list except for a ``clear'' header that
                      causes the current set of headers to be discarded.

       ISO8859        Control the use of ISO 8859-1 encoding in the generated

       ItalicFont     The name of the font to use to set header values (i.e.
                      the string to the right of the ``:'').

       LineWrap       Control whether long text lines are wrapper or truncated
                      at the right hand margin.  (Equivalent to the -c

       MailUser       The account name to use to login to a fax server when
                      doing direct delivery.  Note that this account name is
                      not used for the identity of the sender; this comes from
                      the command line or the ``From'' line in the mail
                      message.  If a null account name is specified, then the
                      facsimile will be submitted using the identity of the
                      user that invoked faxmail.

       MapHeader      Define a substitution for the specified header that
                      should be done each time the header is emitted in the
                      formatted envelope.  Header tags are matched in a case-
                      insensitive manner.

       MarkDiscarded  Control whether discarded MIME parts are replaced by a
                      text message indicating the original content was

       MIMEConverters The pathname of a directory hierarchy that has scripts
                      for external processing of MIME body parts.  The default
                      pathname is /usr/lib/fax/faxmail.

       Orientation    Control whether pages are oriented horizontally
                      (``landscape'') or vertically (``portrait'').
                      (Equivalent to the -r and -R options.)

       OutlineMargin  Control whether columns of text have a line drawn around
                      them and the width of the line.  Setting this parameter
                      to 0 disables outlines.

       PageCollation  Control whether the output file has pages collated in
                      the same order as the input file (``forward'') or in
                      reverse order (``reverse).

       PageHeaders    Control whether page headers are generated.

       PageHeight     Set the output page height (in inches).

       PageMargins    Set the output page margins.  Margins are specified as
                      string of the form: ``l=#,r=#,t=#,b=#'' where l
                      indicates the left margin, r indicates the right margin,
                      t indicates the top margin, b indicates the bottom
                      margin, and numbers are interpreted as inches.
                      (Equivalent to the -M option.)

       PageSize       Set the output page dimensions by name.  (Equivalent to
                      the -s option.)

       PageWidth      Set the output page width (in inches).

       PrologFile     The pathname of a file containing POSTSCRIPT that should
                      be included in the prologue section of the generated
                      POSTSCRIPT.  The default prologue file is

       TabStop        Set the tab stop distance (in characters).

       TextFont       Set the name of font to use for setting text.
                      (Equivalent to the -f option.)

       TextLineHeight Set the vertical text line height and spacing.

       TextPointSize  Set the point size to use in setting plain text.
                      (Equivalent to the -p option.)

       Verbose        Control tracing envelope and MIME processing.

       Because a sender's identity in an electronic mail message is inherently
       untrustworthy, using faxmail to build a mail to fax gateway is
       problematic.  Unless mail service is somehow restricted or the sender's
       identity is verified using a mechanism such as RFC 1847's
       multipart/signed MIME type there is no reliable way to restrict access
       to facilities setup with faxmail.

       Only the last instance of a header is kept and written to the output.
       This means, for example, that only the last of many ``Received'' lines
       will be included in the formatted output.
