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

Yes, I'd love a look at that, thanks.
