Every now and then a message that should be rejected by one of my UCE
filters makes it though to my inbox. Today, three of them did so. I'd like
to learn how to find why the lists aren't working on occasion.
The most frequently involved list is badip (IP addresses in CIDR format).
In main.cf it's found in two lines within smtpd_client_restrictions:
check_client_access hash:/etc/postfix/badip,
check_sender_access hash:/etc/postfix/badip,
Why might a message with the top-most "Received: " header having an IP
address within one of the listed blocks not be rejected?
