NAME
dacsemail - Simple outgoing email agent
SYNOPSIS
dacsemail [-bcc addr] [{-bf | --bodyfile} path] [{-bs | --bodystring} string] [-cc addr] [-ct value] [{-f | --from} from] [-h | --help] [-header name value] [{-mailer | -mta} path] [{-mailer-flags | -mta-flags} string] [-p | --prompt] [-save path] [{-s | --subject} subject] [-sender sender] [{-t | --to} addr] [-transform] [-v | --verbose] [-var name value] 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.
