PBL check last external only #49

Closed fkoyer closed 2 years ago

The PBL list includes end-user IP space. Therefore, it should not be used to check all Received headers. Check last external only.

From https://www.spamhaus.org/faq/section/Spamhaus%20PBL#503:

PBL...should not be used to check all the IP addresses appearing in mail headers.
