You should only see these warnings for mismatched hosts that connect to your Postfix SMTPD server. Do you have a NAT router in front of the Postfix server? Do your logs show all inbound connections coming from only one IP, your public IP address? Do you get this warning for every connection? If so you might try setting http://www.postfix.org/postconf.5.html#proxy_interfaces If all connections are from that one IP, get a different NAT router that doesn't rewrite the source address.
