Postfix not the right tools for doing such filtration, it's MTA, not
antispam or reputation system. Fighting outbound spam is not an easy
task and requires continuous human resources no matter how your antispam
is good, while sender want to send spam he will do it on Nth attempt.

Hello,
I have a question. I've done a lot of research and haven't found a
way to make Postfix work with adaptive delivery (in an easy way).
I have a small ESP and I can't effectively control what emails my
clients send. I have several static rules to allow or not an email
to be sent, but they are static rules.
I would like to know or have some guidance on what to study so that
I can dynamically alert, pause or even stop a send that is receiving
a lot of bounces or is sending and receiving a lot of full box
returns (for example).
Can anyone give me a way forward?

Hi, you can use amavis or spamass-milter also on outbound mail
but this slows down outbound mail ( and may have other problems )
if action by these filters are "hold" you must investigate the hold
mails on a daily term by a human to check if these are false positives
and decide if they should pass, delete or bounce
