       The message conversion filter emil is used to convert the  encoding  of
       enclosures  and  character set of an Internet message aswell as between
       the three message formats  MIME,  SUN  Mailtool  and  plain  old  style
       RFC822.  Emil loads the message and applies the changes in encoding and
       formatting in core. There is no spooling.

       Emil can be applied by sendmail, if specified as a delviery agent,  and
       can  also invoke sendmail or other programs for it’s output.  When used
       like this, emil does not close the connection with the calling sendmail
       until it returns an EX_OK from the called program, as a safety measure.

       Emil can also be used by a mail client program or  as  a  prefix  to  a
       delivery agent like binmail when acting like a regular filter. Usage is
       mainly limited by your imagination.

       Conversion is controlled either by the combination of Sender, Recipient
       and  Recipient_host as specified in the configuration file /etc/
       , by the Target_Group or as specified by the command line options.


       Options may appear in any order.

              -s Sender
                     Sender’s mail address.

              -r Recipient
                     Recipient’s mail address.

              -x Recipient_host
                     Name of the recipient host or relay.

              -f Syslog_facility
                     Pick  one  of:  m  -  LOG_MAIL,  d  -   LOG_DAEMON,   0-7

              -l Syslog_level
                     Log  level  is  set by specifying a number 1-4. Log level
                     becomes: 1 - LOG_ERR, 2 - LOG_NOTICE, 3 - LOG_INFO, 4 and
                     more - LOG_DEBUG.

              -m Mailer
                     Send   output  to  the  specified  Mailer,  where  Mailer
                     corresponds to a mailer definition in  the  configuration

              -i Input_file
                     Path  to  file  for  use  as  input. Defaults to standard

              -o Output_file
                     Path to file for use  as  output.  Defaults  to  standard

              -e Configuration_file
                     Path  to  file for use as configuration file. Defaults to

              -c Charsets_file
                     Path to file  for  use  as  charsets  file.  Defaults  to

       Beware,  when  applying  any  of  the  next  five  options, there is no
       recipient look up in the configuration file.

              -A Recipient_applefile_encoding
                     Recipient   applefile   encoding.   One   of    B(inhex),
                     (apple)d(ouble)  or  (apple)s(ingle).   This  defaults to
                     nothing, thus no applefile conversion if  omitted  unless
                     gotten from the configuration file.

              -B Recipient_binary_encoding
                     Recipient  binary  encoding.  One  of  BAse64,  BInhex or
                     Uuencode.  This  defaults  to  nothing,  thus  no  binary
                     encoding  conversion  if  omitted  unless gotten from the
                     configuration file.

              -C Recipient_charset
                     Recipient charset according to RFC1345.

              -F Recipient_format
                     Recipient  format.  One  of  MIME,  MAILTOOL,  RFC822  or
                     TRANSPARENT. Defaults to RFC822.

              -H Recipient_header_encoding
                     Recipient  header encoding. One of Se, 7bit, 8bit, BAse64
                     or Quoted-printable.  See also

              -T Recipient_text_encoding
                     Recipient text encoding. One of Se, 7bit,  8bit,  BAse64,
                     BInhex,    Quoted-printable   or   Uuencode.   See   also

              -G Target_Group
                     Use Target_Group to specify use of a conversion group, as
                     declared  in  If Target_Group is specified Emil
                     will not try to resolve conversion group using recipient,
                     sender  and  recipient  host,  instead it performs a case
                     sensitive match on the conversion groups as  declared  in
            See also

       Beware,  when  applying  the  Sender_charset option, there is no sender
       look up in the configuration file.

              -S Sender_charset
                     Sender charset according to RFC1345.

              -h Headerlog_level
                     Log in message header.  This  is  for  testing,  not  for
                     production  use.  Log level is specified by a number 1-4.
                     Log level becomes: 1 -  LOG_ERR,  2  -  LOG_NOTICE,  3  -
                     LOG_INFO, 4 and more - LOG_DEBUG.

              -p     Adds a pseudo route to sendmail when using the -f option.
                     Instead of calling sendmail with the recipient’s address,
                     call  with  @EMIL:"recipient address". Used when sendmail
                     is used to call emil, to catch the visit to emil  of  the

              -u     Prepends  a unix from line first in the message/keeps the
                     unix from line if provided in the  incoming  message.  If
                     not  specified  the  unix  from  line will be removed/not

              -g     Test configuration file. Returns the matching group  name
                     based  on  the  provided  recipient, sender and recipient

              -v     Just prints version, then exits.

              -d     Enables debugging  on  stderr.  Using  this  will  create
                     voluminous output.

              -n     Set  up  an  SMTP connection to the host, as specified by
                     the Recipient_host, and send output on  that  connection.
                     This makes Emil act as an SMTP-client, and can be used as
                     a replacement for the tcp mailer of sendmail.


              To use emil as a simple filter:

              %cat | emil [OPTIONS] > message.out


              %emil [OPTIONS] -i -o  message.out

       See the other documentation for further information.
