Questions about Spamhaus
06March
I have gotten a lot of questions about Spamhaus since I’ve been talking about them on the blog and on various mailing lists. Those questions can be condensed and summed up into a single thought. What engagement metrics should I monitor to avoid a Spamhaus listing? First off Spamhaus doesn’t care about about engagement. Spamhaus wants you to stop mailing people who never asked to...

Spamhaus Speaks
05March
There’s been a lot of discussion about Spamhaus, spam traps, and blocking. Today, Spamhaus rep Denny Watson posted on the Spamhaus blog about some of the recent large retailer listings. He provides us with some very useful information about how Spamhaus works, and gives 3 case studies of recent listings specifically for transactional messages to traps. The whole thing is well worth a read...

Another one bites the dust
18January
NASK (the Polish domain registry) has taken over a number of domain names used in spreading viruses and infections. The domain names were used to spread and control dangerous malware known as “Virut” . NASK’s actions are aimed at protecting Internet users from threats that involved the botnet built with Virut-infected machines, such as DDoS attacks, spam and data theft. The scale of the...

Confirming addresses for transactional mail
10December
A colleague was asking about confirming transactional mail today. It seems a couple of big retailers got SBLed today for sending receipts to spamtraps. I talked a few weeks ago about why it’s important to let people unsubscribe from transactional email, and many of those same things apply to confirming receipts. First, let’s look at what Spamhaus has to say. Initially they listed the...

Is Spamhaus still relevant?
14November
Today’s Wednesday question comes from a recent discussion on the Only Influencers mailing list. One of the participants asked “Is Spamhaus relevant and necessary? Are they willing to work with marketers?” I think this is an interesting question for a lot of reasons. One is because there’s such a broad range of opinions about Spamhaus and almost none of them are ambivalent...

What causes Spamhaus CSS listings
26September
Today’s Wednesday Question comes from Zaib F. What causes the Spamhaus CSS listing in your experience other than Sender using multiple sets of IPs, to look as if they are a valid sender. Do you think a Spamtrap plays a role? I’ll preface this by saying I don’t know what the specific Spamhaus criteria are for listing on the CSS. I do know the overall goal of the CSS list is to...

Last week Return Path announce a new set of email intelligence products. One of their new products offers customers the chance to actually see how (some subset of) their customer base interacts with mail directly. It moves beyond simply looking at probe mailboxes and actually looks inside the mailbox of recipients. Spamhaus has listed bit.ly on the Domain Blocklist (DBL) for allowing spammers to...

Questions about CAN SPAM.
10September
In the US, the law governing the sending of commercial email is CAN SPAM. I’ve seen a number of questions about CAN SPAM recently. One came from twitter, where someone was asking if just having an email address meant permission to send to it. Clearly, just being able to dig up an email address doesn’t imply permission to send marketing or commercial email to it. I can promise you...

Spamhaus dDOS
28August
I got mail late last night from one of the Spamhaus peeps telling me that they were under a distributed Denial of Service (dDOS) attack. This is affecting email. Incoming email is delayed and they’re having difficulty sending outgoing email. This is affecting their responses to delisting queries. They are working on mitigation and hopefully will be fully up and running soon. Updates when I...
