This was mostly for my own amusement, since I am always interested in
/who/ is trying to 0wn my boxen, as well as preventing it.

When an exploit attempt is recieved, you get:
Jun 14 23:45:47 victim named[2670]: IQUERY recieved from [192.168.0.20].27447

The patch is for 4.9.6-REL, but it should work accross the board, you get

named may be (is?) the new imapd, with all the bulk scanning that that
implies. You all know the score.
