Spamhaus comments on subscription attack

Steve Linford, CEO of Spamhaus commented on my blog post about the current listings. I’m promoting it here as there is valuable information in it. 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 […]

The 10 worst …

Spamhaus gave a bunch of us a preview of their new “Top 10 worst” (or should that be bottom 10?) lists at M3AAWG. These lists have now been released to the public. The categories they’re measuring are: Countries Spam ISPs Spammers Botnet Countries Botnet ISPs Botnet ASNs TLDs Nothing really surprising there, but it’s nice […]

CBL issues

I started seeing some folks complain about false CBL listings a few hours ago. I’m now seeing the same folks saying the listings are being removed. The symptoms look similar to what happened in November (mentioned here), but it appears the CBL team are on top of things and are working to rectify things quickly.

Dealing with blocklists, deliverability and abuse people

There are a lot of things all of us in the deliverability, abuse and blocklist space have heard, over and over and over again. They’re so common they’re running jokes in the industry. These phrases are used by spammers, but a lot of non-spammers seem to use them as well. The most famous is probably […]

ROKSO lawsuit settled

Earlier this year Ken Magill reported that a judge in the UK was allowing a libel case against Spamhaus to go forward. I thought for sure I’d blogged about the case at the time, but apparently I didn’t. The short version is that today Spamhaus announced the lawsuit was settled and the complainants paid for Spamhaus’ […]

Email verification services

Just yesterday a group of delivery folks were discussing email verification services over IRC. We were talking about the pros and cons, when we’d suggest using them, when we wouldn’t, which ones we’ve worked with and what our experiences have been. I’ve been contemplating writing up some of my thoughts about verification services but it’s a […]

The true facts of spam traps and typo traps

I’m seeing an increase in the number of articles stating wildly wrong things about spam traps. Some have started claiming that typo traps are new. Or that typo traps are newly used by Spamhaus. These claims make for great copy, I guess. Wild claims about how the evil anti-commerce self-appointed internet police are actively trying to trap […]
