Monitor Que Lengths

[Steve Evans]

We're still on 2.6 or something like that.  We starting using Mailscanner in December just before 3.x came out so we've never upgraded yet.  We probably will next month after things calm down a bit.

Thanks for the script idea.  I should probably also have the script check mqueue also shouldn't I.

What version of MailScanner are you using? This was a known problem with
some of the early releases of version 3. You really need to be running 3.04.

Running /usr/local/MailScanner/bin/check_mailscanner should restart
MailScanner if it is not running.

How about something like

#!/bin/sh

# Define this to be your maximum allowed mail queue length
MAXLEN=300

LSLEN=`cd /var/spool/mqueue.in && ls | wc -l`
QUEUELEN=`expr $LSLEN / 2`
if [ $QUEUELEN -gt $MAXLEN ]; then
   /sbin/reboot
fi
