Had trouble with your IPs being listed on the Protected Sky blacklist (bad.psky.me)? You’re not alone. Since the blacklist came onto the scene in 2015, many senders have bemoaned the lack of delisting process and high rate of false positives, as well as the inability to contact anyone working for the list provider.

Recently, Spamhaus issued a statement revealing that this list was fraudulently republishing IP listings from the Spamhaus blacklists by siphoning the data from a user of the Spamhaus data feeds. The affected user has since added security measures to prevent this data from being passed to Protected Sky.

Personally, I’m not sure I’ve ever seen mail rejected solely due to a Protected Sky listing, but after this announcement it’s a pretty safe bet that anyone left using the list likely won’t be doing so for long.

Thanks to Laura at Word to the Wise for the heads up on Spamhaus’ statement.
