It’s been one of those weeks where blogging is a challenge. Not because I don’t have much to say, but because I don’t have much constructive to say. Rants can be entertaining, even to write. But they’re not very helpful in terms of what do we need to change and how do we move forward. A few different things I read or saw brought out the rants this week. Some of these are...
Earlier this week, the investment firm Marlin Equity Partners announced they purchased BlueHornet Networks from Digital River. BlueHornet has been around for quite a while. In 2004 they were acquired by Digital River and run as a wholly owned subsidiary.
Congrats to the folks working at BlueHornet.
As we head into the last month of the year, we look back at our November adventures. I spoke twice this month, first at Message Systems Insight in Monterey (my wrap-up post is here) and then with Ken Magill at the at the 2015 All About eMail Virtual Conference & Expo (a short follow-up here, and a longer post on filters that came out of that discussion here.). Both were fun and engaging...
The nice folks over at Sparkpost asked me and other email experts for some thoughts on what we think the most important issues in email will be in 2016. I do think security is going to be a major, major change in delivery. From what I’ve seen there’s been a shift in the mindset of a lot of people. Previously a lot of folks in the email space were very accommodating to old systems and...
The CBL issued a statement and explanation for the false positives. Copying it here because there doesn’t seem to be a way to link directly to the statement on the CBL front page. November 24, 2015 Widespread false positives Earlier today, a very large scale Kelihos botnet event occured – by large scale, many email installations will be seeing in excess of 20% kelihos spam, and some...
Update: As of Nov 24, 2015 11:18 Pacific, Spamhaus has rebuilt the zone and removed the broken entries. Expect the new data to propagate in 10 – 15 minutes. Delivery should be back to normal. The CBL issued a statement, which I reposted for readers that find this post in the future. I think it’s important to remember there is a lot of malicious traffic out there and that malicious...
I posted Friday about how most deliverability folks roll their eyes when a sender starts talking about their business model. The irony is that one of the first things I do with a client is ask them to tell me about their business model and how email fits into their business plan. Once I know that, I can help them improve their email sending to meet the requirements of ISPs, blocklists and...
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 “I’m sure they’ll unblock me if I can just explain my business model...
Kevin Senne posted over on the Oracle blog about how we need to stop caring about SenderScore and why it’s not as useful a metric as it used to be. I can’t argue with anything he’s said. I think there is way too much focus on IP reputation and SenderScore. There’s so much more to deliverability than just one or two factors. In fact, if you’ve been to any of my recent...
Earlier today I approved a comment from Mike on a post about problems at AOL from 2012. The part of the comment that caught my attention: SMTP error from remote mail server after end of data: 521 5.2.1 : AOL will not accept delivery of this message. Mike also mentioned his IP reputation is good, when he checks at AOL so he doesn’t understand why mail is being blocked. I think the big clue...
