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.
DELIVER on VAX/VMS had user based rejection based on the from field in
the late 1980's as I recall using it then. Downloadable of DELIVER are

Reference to DELIVER in 1989 here:

I also built a GUI front end to procmail and mention an "auto delete"
feature based on certain rules. This thesis was written in late
1993/early 1994 and subsequently published by SIGS in Object Currents
magazine. 10 years later I know that students were still referring to
the thesis, so I guess there are citations in other theses which could
be checked. My thesis is available online here:
http://www.siliconglen.com/craig/cv.html and has been available on the
web since Jan 1996.
