You will probably find that those delivery attempts tend to try the
secondary mx first, if you have one.  One way to harvest the known bad
senders would be to set up one or more dummy backup MXes whose sole
purpose is to run a greylisting spamd with greytrapping.  The next
step would then be a blacklisting-only spamd in front of your real MX
using frequent dumps of your greytrapped IP addresses, likely
supplemented by something like uatraps.  Most likely not as effective
as greylisting with greytrapping all around, but it would give you
some of the benefits of greytrapping.
