I am seeing login dictionary attacks on a FreeBSD mail server being

I wrote some code to find the appropriate maillog entries which do
include the IP addresses. It automagically adds the IP addresses to
the pf blackhole table if certain criteria is met. The criteria is
changeable. If you would like a copy, let me know.
That sounds incredibly useful. Can you post it somewhere?
