##
##  This is a sample jobcontrol program for HylaFAX that can be used
##   to Virtualize a fax service for various "client" companies in a
##   single HylaFAX installation
##
##  This virtualization does a few things:
##    1) Verifies client
##    2) Rejects jobs that the client submitted that we consider
##       Malicious
##    3) Set's Modem based on destination and client settings
##    4) Set's faxsend options to make the job appear from the client's own
##       FAX service
##
##  This assumes that by default, faxsend is configured not allow TSI
##   modification, and is branded with our fax service branding/numbers/etc.
##
##  To get full milage from this type of JobControl, you should have the
##   following settings in $SPOOL/etc/config for FaxQueuer:
##	MaxBatchJobs: 1
##	JobControlCmd: bin/jcontrol.sh
##	JobControlWait: false
##

JOBID=$1

## GetClient <owner> <email>
##  - returns a string - the client identifier

## Result of "REJECT" is a non-authorized submitter, and
##  should be rejected.
## Result of "" means it's not a virtualized client and 
##  should be subject to our default modem settings
GetClient ()
{
    # Pretend to lookup the user
    case "$1" in
#	aidan)
#	    echo "1234"
#	    ;;
#	root)
#	    echo "REJECT"
#	    ;;
	*)
	    # All others are not full virtual clients
	    echo ""
    esac
}

##
## GetJobParam <param>
## - returns the value of the job param
GetJobParam ()
{
	grep "^$1:" sendq/q$JOBID | cut -d : -f 2-
}

    exit
