Hello all. I'm trying to block some TLDs and everything I try I'm
getting: 451 4.3.5 <em...@gmail.com>: Sender address rejected: Server
configuration error;
Obviously this is a configuration issue. I've tried following these
sites among others:
https://forum.centos-webpanel.com/index.php?topic=10649.0
https://www.davidmartinwhite.com/2016/10/25/fighting-spam-block-entire-ttld-with-postfix/
https://www.ericmichaelstone.com/how-to-block-an-entire-tld-in-postfix/
Hoping there's and easy fix in my configuration. Sorry, not a postfix
expert. If you see any issues in my config I would appreciate
suggestions.
Thanks
