caching information about bouncing receipients?

Hi,

is there a builtin way to make postfix remember bouncing recipient
addresses, so that further attempts to send mails to those addresses
can be rejected?

I do NOT want to use active recipient address verification. I only want
to save when a real mail delivery attempt fails - so this seems to be
kind of "passive address verification during mail delivery".

Thanks and regards
