Here's the issue that is resolved in 1.37 that breaks whitelisting: https://github.com/schweikert/postgrey/issues/45
The latest Postgrey release is now almost three years old and is not in
Debian. Some of the whitelist configuration options don't work in the
version in Debian now, making it impossible to receive emails from
certain senders. Any chance someone can turn to this? Even an NMU?
