I don't run postifx and the thing I am about to mention I have not
tried yet, but you may want to explore modifying your greylisting to
be based on spamassassin results.
I use exim as the mta and there is a thing called sa-exim that lets
you run spamassassin at SMTP time so that you can reject mail if you
want before you actually are finished receiving it. The author of sa-
exim has modified it to do greylisting based on spamassassing scores
generated at smtp time, so that you only greylist mail that is
thought to be spam and do not inconvenience your regular users.
Can you do spamassassin at smtp time with postfix?
