DESCRIPTION
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 delivery 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
/usr/local/lib/emil.cf , by the Target_Group or as specified by the
command line options.
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
LOG_LOCAL[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 corre‐
sponds to a mailer definition in the configuration file
emil.cf.
-i Input_file
Path to file for use as input. Defaults to standard
input.
-o Output_file
Path to file for use as output. Defaults to standard out‐
put.
-e Configuration_file
Path to file for use as configuration file. Defaults to
/usr/local/lib/emil.cf
-c Charsets_file
Path to file for use as charsets file. Defaults to
/usr/local/lib/charsets.cpl
Beware, when applying any of the next five options, there is no recipi‐
ent 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 Uuen‐
code. This defaults to nothing, thus no binary encoding
conversion if omitted unless gotten from the configura‐
tion file.
-C Recipient_charset
Recipient charset according to RFC1345.
-F Recipient_format
Recipient format. One of MIME, MAILTOOL, RFC822 or TRANS‐
PARENT. Defaults to RFC822.
-H Recipient_header_encoding
Recipient header encoding. One of Se, 7bit, 8bit, BAse64
or Quoted-printable. See also emil.cf(1).
-T Recipient_text_encoding
Recipient text encoding. One of Se, 7bit, 8bit, BAse64,
BInhex, Quoted-printable or Uuencode. See also
emil.cf(1).
-G Target_Group
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(1).
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 pro‐
duction 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
message.
-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
prepended.
-g Test configuration file. Returns the matching group name
based on the provided recipient, sender and recipient
host.
-v Just prints version, then exits.
-d Enables debugging on stderr. Using this will create volu‐
minous 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.
EXAMPLES
To use emil as a simple filter:
%cat message.in | emil [OPTIONS] > message.out
or
%emil [OPTIONS] -i message.in -o message.out
See the other documentation for further information.
