Requeue messages based on script output?

Hi,

I have a recipe that invokes a script which inserts data into a database
based on a custom parsing routine. 

That is all working fine, however sometime the database in question will be
down for one reason or another.

When this happens, I want procmail to abort processing and requeue the
message for later processing.

My current script is:


########################## procmailrc ###########################
##                                                             ##
## Processes incoming mail and passes messages to the mail     ##
## processing script.                                          ##
##                                                             ##
## Last Modified on 02/04/2003 by MAA                          ##
##                                                             ##
#################################################################


###################### Variable Declaration #####################

LOGFILE="${HOME}/scripts/logs/"`date +"%y%m%d"`"_procmail.log"
DEFAULT="${HOME}/Mail/incoming/"`date +"%m%d%y"`

DB_CHECK="${HOME}/scripts/db_check.sh"
PROCESSOR="${HOME}/scripts/MailProcessor.sh"

# VERBOSE=yes

####################### Recipie Execution #######################

LOCKFILE=procmail.lock          # Create the lockfile, ensuring 
                                # one procmail process at a time

:0wc
| echo "---" >> $LOGFILE        # Message seperator (readability)


:0wci
| $DB_CHECK                     # Verify DB online

DB_ONLINE = $?                  # Capture the return value


:0                              # Is the DB offline?
* ! $DB_ONLINE ?? 0
{
        EXITCODE = 75           # Requeue the message
        LOCKFILE                # Release the lock file
        HOST                    # Exit immediatly
}


:0wci
| mkdir -m 755 -p $DEFAULT      # Make sure mail directory exists


:0wc
$DEFAULT                        # Save message to mail directory


MESSAGEFILE = $LASTFOLDER       # Capture path of saved message


:0w
| $PROCESSOR $MESSAGEFILE       # Pass message to mail processor


LOCKFILE                        # Release the lockfile


########################## End of File ##########################



Everything is working fine except the requeuing. I had done some searching
and found that setting the EXITCODE to 75 results in requeuing, so I put it
in, but the message never gets reprocessed.

What am I doing wrong? Help!
