[GRLUG] Bash split question, ..

[Godwin]

I suspect what you're after is auto cleaning of the mail queue.  Here are a
couple of things I do that may help...

this (theoretically) issues a call to the 'postsuper' command with a single
parameter until it exhausts the list of problematic email entries in the
queue.

cron entry (run every 10 mins):
# Delete MAILER-DAEMON entries from mail queue
*/10 * * * * /etc/postfix/scripts/queue-cleanup.sh

[me at smtp me]% less /etc/postfix/scripts/queue-cleanup.sh
#!/bin/bash

/usr/bin/mailq |grep --color=none MAILER-DAEMON | awk '{print $1}' | tr -d
'*!' | xargs -n 1 postsuper -d >/dev/null 2>&1
--------------------------------------------------------------------------------

And this let's me know which messages are being HELD (I hold some based on a
criterion).

[me at smtp me]% crontab -l|grep -i mailq
*/10 * * * * /home/users/me/bin/monitor_mailq.sh
[me at smtp me]% less ./bin/monitor_mailq.sh


------------------------------------------------------------------------------------
#!/bin/bash

# This script will monitor the mail queue for messages on HOLD
# and e-mail me if/when it finds one.

recipient=operator
HELD=`/usr/sbin/postqueue -p | grep \! | cut -d'!' -f1`

if [ ! -z "$HELD" ]; then
  echo "Message id $HELD is being held for review." | mail -s "Message HELD"
$recipient
fi
------------------------------------------------------------------------------------
