If you have a fixed "menu" of restriction settings,
"spam-lover", "spam-hater", "spam-neutral", ...
you can add as many domains as you wish by mapping each domain to one
of the fixed restriction settings. If you want fully custom settings for
each domain, and want to scale this to many domains, Postfix is not the
right tool, you need a milter or pre-queue proxy filter.
