No. What I am saying is that when we started implementing block lists,
it was immediately obvious that having *per-user* block lists would be
useful, and that is what I have been doing since around '96.
Let's not forget that procmail allowed per-user block lists in December
1990. Certainly by 1994 I was using it to return an SMTP error to
someone who mailbombed me, by passing an error code back to sendmail
from my .forward file.
So not only is the patented technique obvious, it has a good decade of
prior art through common usage.
Sadly that isn't enough to stop a software patent being issued and
upheld. It amazes me that anyone would think that per-user block lists
are actually an ingenious invention that deserves a patent.
