[EXIM] Wiping lots of messages from the queue

I have run into a nasty loop problem and I have thousands of messages in
my queue that I want to kill. However, there are a few legitimate messages
in there too. Can someone help me with a command line that achieves the
following:

pick the files that are junk somehow:

Something like:

grep -l Daemon /var/spool/exim/input

"Give up" on them:

Something like:

exim -Mg


I can't quite get these to work together...

Please help!

Ben
