The smtpd_recipient_restrictions is a superset of all of the others.
I put all of my restrictions there. It might be good to pastebin the
entirety of your smtpd_recipient_restrictions section.
You don't mention DNSBLs. If you are not using them then that would
be a large lever to improve your anti-spam efforts. I highly
recommend doing at least this in smtpd_recipient_restrictions:
reject_rbl_client zen.spamhaus.org
You can read about the zen DNSBL here:
