- if they asked for notifications but don't accept them, it's their
problem. Inundate them (you may need to run a cron job to send mail to
their admins, boss and their families, until they fix their system ;-p).
- if they didn't ask for, why do you send them notifications?

you can't do per envelope AND per content checks without a content
filter or without convoluted setups.
if you're ready for convolution, run a specific instance (so that you
can play with transport_maps). in the "primary" instance, redirect the
problem domain to the second instance. and in this, use header_checks to
catch the problem mail (use HOLD, REDIRECT or whatever appropriate).
you can do this with a single instance by passing through a specific
filter that uses header checks to run another filter which does smtpd
restrictions... if you do this, get out and find an open bar where you
can drink until the morning. and when you get out, kill a cat or a dog,
otherwise, you won't get your photo in the newspapers (except maybe in
the Washington Postfix).
