Asking for help with a blocklist

That document was aimed primarily at MAAWG members and deliverability experts with working knowledge of blocklists. I think, even […]

How many blocklists do we need?

This discussion wandered around a little bit, but started me thinking […]

Excellent well summarized article Laura 🙂 No we’ve not changed SBL policy to require COI. It’s something we very strongly advise but we can not make a requirement. We’ll have […]

Fake DNSBLs

Spamhaus recently announced a few years ago that they have discovered a company that is pirating various blocklists, relabeling them and selling access to them. Not only is the company distributing the zones, they’re also running a “pay to delist” scheme whereby senders are told if they pay money, they’ll be removed from the lists. […]
