rdeliver

rdeliver(1)						      General Commands Manual						       rdeliver(1)

NAME

       rdeliver - Ruby mail filter script

SYNOPSYS

       rdeliver <options> [script]

DESCRIPTION

       This  script  serves  as  an  example  of how you can use the RFilter::DeliveryAgent class to perform mail delivery.  You can also use this
       script as a fully functioning mail filter.

       This script is a basic mail local delivery agent (DeliveryAgent) that can be used in place of procmail, maildrop, etc. in a user's .forward
       or  .qmail  file.  The user supplies a delivery script that is written in Ruby, which avoids the limitations of the crippled mini-languages
       so often used in other DeliveryAgent programs.

USAGE

       rdeliver is invoked from the command line using:

	      % rdeliver <options> [script]

       The script argument is optional.  If omitted the script will look for a file called .rdeliver in the home directory.

       Options are:

       --load-path directory
	      Prepend the given directory to ruby's load path.

       --log filename
	      Log to the given filename.  If no log is specified, no logging occurs.

       --home directory
	      Specify the home directory.  rdeliver will change to this directory before reading  and  writing	any  files.   The  home  directory
	      defaults to the value of the HOME or LOGDIR environment variable.

DELIVERY SCRIPT

       The  delivery script runs in the context of a class called Deliver (in contrast, most ruby scripts run in the context of the Object class).
       So any methods added with def will be added to the Deliver class.

       A minimal delivery script would be:

	       def main
		 agent.save('inbox')
	       end

       This code defines a Deliver#main method that saves the mail into an mbox style mailbox.

       The only API the Deliver script has is the #agent method.  This retrieves the RFilter::DeliveryAgent object  associated	with  the  current
       message.   Using  the API of the RFilter::DeliveryAgent object, you can access and modify the message body and headers, defer or reject the
       message delivery, and deliver into various mailbox formats.

       See also RFilter::DeliveryAgent and Deliver.

INSTALLATION

       Assuming you have the RubyMail mail classes installed, you typically have to put something like this in your .forward file:

	      |"/usr/bin/rdeliver --log /home/you/.rlog"

       This will call rdeliver for each new message you get, and log to /home/you/.rlog.

CATASTROPHIC ERRORS

       The rdeliver script is very careful with errors.  If there is any problem, it logs the error to the log file you specify.  But  if  you	do
       not  specify  a	log  file, or the error occurs before the log file is opened, a record of the error is placed in a file called CATASTROPH-
       IC_DELIVERY_FAILURE in the home directory.  If that fails, the error information is printed to the standard output in  the  hopes  that	it
       will be part of a bounce message.  In all cases, the exit code 75 is returned, which tells the MTA to re-try the delivery again.
