You can send X amount of mails in Y time period. If the sender hits that 
limit,
an "abuse" log entry is triggered to indicate that the limit is reached 
and further
mails are "attempt" to be sent. When the rolling time window is reached,
mails will be allowed to flow as normal.

I stand corrected but i believe the same behaviour applies to Policyd v2.

Correct. Instead of modifying the code to execute other tools, I recommend
using syslog-ng and use it to perform various types of triggers since it has
been designed to cater for what you want. (match for abuse logs, execute
tool).
