Can someone help me understand how this IP is being rejected?

Jan 22 05:51:11 mail03 postfix/smtpd[21852]: NOQUEUE: reject: RCPT

it's actually not an IP being rejected. "Sender address rejected" means
sender rejection

Yes, thank you, I should have included it all originally. I've
searched for '209.85' in all of the local postfix files and the only
occurrence is "209.85.128.0/17   permit" in gmail_whitelist.cidr,
updated regularly.

smtpd_recipient_restrictions =
       reject_rhsbl_sender mykey.dbl.dq.spamhaus.net,

check this one

       check_sender_access hash:/etc/postfix/check_backscatterer,

and this one.
