I actually have a number of live/active users on my test server, but
I see your point. Of course, everyone gets different email, so I'm
wondering how large the difference really is.

Do you mean greylist for specific users or specific incoming email
domains? This is what I was considering, a per-user opt-in approach.
I just have to look into how to get Postfix to look up the policies
to use. I can insert it before or after alias expansion with my
setup (Postfix is so flexible :)), but I guess that's beside the point.

This is what I'll probably do, make a web interface, but I was
thinking about using an SQL lookup in Postfix to get the policies
(not sure if that is possible) and/or putting it in amavisd-new or
something so you can have "trickle-down" organization-based
policies. If this isn't possible, adding it to sqlgrey may be the
only option, but I think it "belongs" in Postfix, personally.

Anyway thanks for the response!
