Spamhaus: The return of the ASN-DROP


Spamhaus just announced that they've "reinvigorated" the ASN-DROP list, now available in JSON format. The point of this whole thing is for network operators (think ISPs and similar) to just totally block off any potential connections with really bad networks that are spewing nothing but spam, phish and other garbage.

In theory this should not impact your typical marketing sender, but it's good all of us to be aware of what this is. They're blocking, in some cases, some bad guys who would happily take threats to a phyiscal level with Spamhaus people, given the chance. If the bad guys can't route their bad stuff, they can't rip people off, and they don't make as much (ill gotten) money. That's why Spamhaus folks are sometimes cagey about full names and locations, in case you're wondering -- not because they're worried about how a Fortune 500 retailer might react to an SBL issue.

You're not sure what Spamhaus is or what any of this stuff means? Here's a good place to start.
