NAME

     extsmail.conf — configure robust sending of e-mail to external commands

DESCRIPTION

     extsmail.conf is used to configure extsmail(1) and extsmaild(1).  It consists of one or more
     key = value pairs. The following variables are defined:

     spool_dir
             Sets the location of the spool directory used by extsmail(1) and extsmaild(1).  This
             is the only variable which must be set in every configuration file.

     notify_failure_interval
             Specifies how often notifications of unsucessful deliveries should be made.  If
             unspecified, or set to 0, notifications will never be made. Times are specified as a
             number followed by d (days), h (hours), m (minutes), or s (seconds).

     notify_failure_cmd
             The shell command to be executed when notify_failure_interval seconds / minutes /
             hours / days have elapsed since the last fully successful send cycle. If the string
             ${TIME} exists in the command, it is replaced with a pretty printed string detailing
             how much time has elapsed since the last fully successfuly send cycle.  The
             resulting string is then passed to system(3).  Note that no security checking is (or
             can be) done on the command, so this option should be used with caution if a single
             configuration file serves multiple users. Please check the warnings that come with
             system(3).

     notify_success_cmd
             The shell command to be executed when 1 or more messages have been successfully
             sent. If the string ${SUCCESSES} exists in the command, it is replaced with a string
             representing the number of successfully sent messages. The same warnings that apply
             to notify_failure_cmd also apply to this command.

FILES

     The extsmail configuration file is searched for, in order, in the following locations:

     ~/.extsmail/conf
             Per-user extsmail configuration.

     /etc/extsmail/conf
             System-wide extsmail configuration.

EXAMPLES

     The simplest configuration file looks as follows:

           spool_dir = "~/somewhere"

     A more complex configuration which uses a notification framework to inform the user of mail
     sending and failure looks as follows:

           spool_dir = "~/somewhere"
           notify_failure_interval = 30m
           notify_failure_cmd = "notify-send -a extsmaild -c email
             -i mail-send -u critical 'extsmaild: ${TIME} since a fully
             successful send cycle'"
           notify_success_cmd = "notify-send -a extsmaild -c email
             -i mail-send -u low 'extsmaild: ${SUCCESSES} messages
             successfully sent'"
