I would like to delete some messages from an existing postfix queue based on a string match in the message body. Any suggestions?

This is fairly simple:

find /var/spool/postfix/deferred/ -type f \
        -exec grep -l 'body string here' '{}' \; | \
    xargs -n1 basename | xargs -n1 postsuper -d

Adjust path (if non-default), and the -n1 in the second xargs isn't strictly needed, but gives a better sense that it's actually doing something.

He didn't specify which queue. – adaptr Apr 25 '12 at 8:17
True. For a different queue, use that instead of deferred in the find portion. postsuper works on a number of queues -- hold, incoming, active and deferred -- or you can specify it at the end ( ... | xargs -n1 -i postsuper -d '{}' bounce ) – techieb0y Apr 27 '12 at 1:09

Perhaps you should end that with > delfile.txt then you can review what you deleted and then delete the text file
