A way to do this would be to use transaction-level filtering instead of the kill file. The settings are found in MercuryS configuration / Compliance. In your case a line like this might work:
M, "*badguy@somedomain.com*", B, "554 You have been permanently rejected"
There is more info on how to write transaction filtering rules in Mercury help.
