Hi, I see you have gotten plenty of good responses, but here is how I deal with
it.
Once I know what I am looking for.... from the command line I do this, and it
is pretty fast for 1 to 2 thousand emails at a time.
These are some recent examples I used to clean things up, that were sitting
there for days already.
HOLD queue:
postqueue -p|grep match.com|awk '{print $1}'|sed -r 's/!//'|while read id; do
postsuper -d $id;done
Deferred queue:
postqueue -p|grep MAILER|awk '{print $1}'|while read id; do postsuper -d
$id;done

I have already made similar scripts, but the issue is that it runs "postcat"
and "postsuper" once for every queue ID, so it becomes absolutely unusable
when needing to delete tens- or hundreds of thousands of emails.
So far I have been lucky in that most of spam scripts send mail with only a
few different sender email addresses, so I've been able to grep the output
of "postqueue -p" 4-5 times, used Vim to create a long list of queue IDs and
fed it to "postsuper -d -" through the standard input.
However, I'm never sure I've caught all the spam mails sent from the
specific IP, and some day I could have to clean up the spam of a script that
generates random sender email addresses. That day I'm going to need a fast
script that can filter queue IDs by sender IP.
I really, really wish "postcat -e" had a "-" option, like postsuper, that
allowed me to stream queue IDs in through stdin...
