A place where users can report and comment on usage of the APEWS.ORG blocklist as an antispam measure on email servers. In particular the focus is to publish errors, known as false positives, in response to the decline in usefulness of Usenet where formerly there were "sightings" and "blocklists" newsgroups.

Whitelist included
Whilst checking the dataset of l2.APEWS.org (using the dnsbl editor), we found that there are now exclude records in the dataset, lots of them. When email servers use a dnsbl they send a lookup query but if the IP address exists as an exclude record, the lookup query will return "unlisted". It looks like thousands of IP addresses from whitelists have been included in this way so the chance of errors now is greatly reduced. Certainly we've had none to report for a while as you will have noticed. Checking some of those whitelisted IP addresses and they are those of trusted senders.
