first – you want to get the postfix-delete.pl script from here:
http://www.cyberciti.biz/tips/howto-postfix-flush-mail-queue.html
Next – create a script to inspect the mailq and then a single message – finally, ask if the message should be deleted – very linear script..
#!/bin/sh cd /var/spool/postfix/deferred/; MAILQCHECK=`mailq`; if [ "$MAILQCHECK" = "Mail queue is empty" ] then echo $MAILQCHECK; exit 0; fi ## ## if we get here, the mailq is not empty... ## echo $MAILQCHECK | more; echo 'Enter mail ID to inspect:'; read MAILID; if [ "$MAILID" != "" ] then strings */$MAILID | more; echo 'Delete?' read SHALLIDELETE; SHALLIDELETE=`echo $SHALLIDELETE| tr '[a-z]' '[A-Z]'`; export SHALLIDELETE; if [ "$SHALLIDELETE" = "Y" ] then ## ## get the postfix-delete.pl from http://www.cyberciti.biz/tips/howto-postfix-flush-mail-queue.html ## /root/postfix-delete.pl $MAILID ; exit 0; else echo 'exiting without delete...'; exit 0; fi else ## ## they didn't enter an ID - exit ## echo 'exiting...'; exit 0; fi
