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/emil.cf
, by the Target_Group or as specified by the command line options.
Options may appear in any order.
Sender’s mail address.
Recipient’s mail address.
Name of the recipient host or relay.
Pick one of: m - LOG_MAIL, d - LOG_DAEMON, 0-7
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.
Send output to the specified Mailer, where Mailer
corresponds to a mailer definition in the configuration

Beware, when applying any of the next five options, there is no
recipient look up in the configuration file.
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.
Recipient binary encoding. One of BAse64, BInhex or
Uuencode. This defaults to nothing, thus no binary
encoding conversion if omitted unless gotten from the
Recipient charset according to RFC1345.
Recipient format. One of MIME, MAILTOOL, RFC822 or
TRANSPARENT. Defaults to RFC822.
Recipient header encoding. One of Se, 7bit, 8bit, BAse64
or Quoted-printable. See also emil.cf(5).
Recipient text encoding. One of Se, 7bit, 8bit, BAse64,
BInhex, Quoted-printable or Uuencode. See also
Use Target_Group to specify use of a conversion group, as
declared in emil.cf. 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
emil.cf. See also emil.cf(5).
Beware, when applying the Sender_charset option, there is no sender
look up in the configuration file.
Sender charset according to RFC1345.
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
-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 message.in | emil [OPTIONS] > message.out
%emil [OPTIONS] -i message.in -o message.out
