       dacsemail --version

DESCRIPTION

       This program is part of the DACS suite.

       The dacsemail utility is a simple agent for sending email messages. It is a stand-alone program that
       neither accepts the usual DACS command line options (dacsoptions[1]) nor accesses any DACS configuration
       files.

       dacsemail constructs an RFC 822[2] format message but does not transmit it. It requires an external
       mailer, such as sendmail(8)[3], to transfer the message. The mailer command and its arguments can be
       specified on the dacsemail command line (see -mailer) or at build time (see dacs.install(7)[4]).

OPTIONS

If the source for the message body is not specified on the command line, it will be read from the
standard input. At least one recipient must be specified using -t, -cc, or -bcc.

-bcc addr
Send the message to the undisclosed recipient address addr. It is the responsibility of the mailer to
delete these recipient addresses before transmitting the message. This flag may be repeated.

-bf path
--bodyfile path
Read the message body from path. If path is -, the standard input is read.

-bs string
--bodystring string
Use string as the message body.

-cc addr
Send the message to recipient addr as a carbon copy. This flag may be repeated.

-ct value
Add a Content-type header of MIME type value to the message. If value is multipart/alternative, an
appropriate boundary variable will be created, unless one has already been specified on the command
line with the -var flag. It is assumed that the message body has already been correctly formatted for
this MIME type, or will be after it has been transformed (see -transform).

-f from
--from from
Use from as the value of the message's From header.

-h
--help
Print usage information and then exit.

-header name value
Add a message header named name with value value. This flag should only be used for headers that do
not have specific flags (-t, -ct, -f, and so on).

-mailer path
-mta path
Use the message transfer agent command path (a full pathname) instead of the configured program. This
program must read the message from its standard input and extract the list of recipients from the
message's To, Cc, and Bcc headers. (If such a mailer is unavailable, it will be necessary to write a
small program to wrap a mailer and provide the required interface to dacsemail.) The default is to
run sendmail(8)[3] with its -t flag.

-mailer-flags string
-mta-flags string
Regardless of the mailer, use string for its command line flags.

-p
--prompt
Just before the message is to be sent, display it (to stderr) and wait for the user to respond to a
prompt. At the prompt, the user may abort the message or allow it to be sent.

-save path
Just before sending (or prompting), write a copy of the outgoing message to path, replacing any
previous contents of the file.

-s subject
--subject subject
Set the message's Subject header to subject.

-sender sender
Set the message's Sender header to sender.

-t addr
--to addr
Add addr as a "To" recipient. This flag may be repeated.

-transform
The message body, regardless of how it is specified, is filtered through the DACS transformation
function. Please refer to dacs_transform(8)[5] for details. No access control rules may be associated
with any transformation; i.e., they are all unconditional. A similar effect can be obtained by piping
the output of dacstransform(1)[6] into dacsemail.

-v
--verbose
Enable verbose output for debugging.

--version
Display the program's version information and then exit.

-var name value
Create a variable[7] named name set to value for the transform function. The variable's value can be
referenced within the message body in the DACS namespace as ${DACS::name}. The variable must not
already be defined.

EXAMPLES

       Suppose myfile contains the following text:

           <!--DACS expand="*" -->
           This is a multi-part message in MIME format.

           --${DACS::boundary}
           Content-Type: text/plain; charset=us-ascii
           Content-Disposition: inline
           Content-Transfer-Encoding: 7bit

           Hello, ${DACS::user}!

           --${DACS::boundary}
           Content-Type: text/html; charset=us-ascii
           Content-Disposition: inline
           Content-Transfer-Encoding: 7bit

           <p>
           <font color="red">Hello, ${DACS::user}!</font>
           </p>
           --${DACS::boundary}--
           <!--DACS end="*" -->

       The following command might be used to send a message with a multipart/alternative structured body:

           % dacsemail -ct multipart/alternative -f auggie@example.com \
                 -t harley@example.com -s "Hello" -transform -var user Auggie -bf myfile

       The resulting message will look something like the following:

           To: harley@example.com
           From: auggie@example.com
           Subject: Hello
           Content-type: multipart/alternative; boundary="_----------=_03885942562898683484"
           Date: Wed, 07 Apr 2010 16:48:41 -0700 (PDT)
           Content-transfer-encoding: 7bit
           X-mailer: DACS 1.4.24a

           This is a multi-part message in MIME format.

           --_----------=_03885942562898683484
           Content-Type: text/plain; charset=us-ascii
           Content-Disposition: inline
           Content-Transfer-Encoding: 7bit

           Hello, Auggie!

           --_----------=_03885942562898683484
           Content-Type: text/html; charset=us-ascii
           Content-Disposition: inline
           Content-Transfer-Encoding: 7bit

           <p>
           <font color="red">Hello, Auggie!</font>
           </p>

           --_----------=_03885942562898683484--

FILES

       None.

DIAGNOSTICS

       The program exits 0 if everything was fine, 1 if an error occurred. Error messages are printed to stderr.
       Errors and routine messages from the mailer are recorded wherever they are normally logged, outside of
       DACS

BUGS

       This program's primary purpose is for testing DACS functionality that is needed for internal purposes. No
       significant improvements are envisioned. You could throw a rock and hit a better email agent.
