New Server (Take #2)

The Mainsleaze Blog has moved to yet another new server, this one running CentOS 7. Everything appears to be working properly, including the pages and links that were broken on the first server. Please review the site, attempt to post comments, etc. If nothing breaks for the next 48 hours, I will declare victory and shut down the old server for good. 🙂

Thank you, everybody, for your patience!

Back on the Old Server

The Mainsleaze blog moved to a new server over the weekend. A number of odd bugs ensured. A day’s research and efforts to fix the problems exposed some serious underlying bugs in the most recent version of the underlying operating system on the server. We reverted to the old server til we can get the new server properly debugged or upgrade to a less buggy OS.

Sorry for the delays! 🙂

April 2016 in Spamtraps: ESPs (and only a word or two about Social Networks)

ESP mail seen in spamtraps April 2016

The percentage of ESP sent mail vs all mail seen in the spamtraps is back to normal levels, 1.5% this month. Social networks account for 3.9% of all mail, of which nearly 93% is Facebook. Facebook is “only” sending 2.5 times as much mail as all tracked ESPs combined, which would be a reduction of 30%… if it wasn’t the case that ESPs were sending more mail than last month, and Facebook was simply keeping up their old levels.

Filip Poutintsev, Spam Apologist

A recent post on LinkedIn from Finland’s finest is claiming to debunk all the arguments for why spam might be bad.

Filip, it doesn’t occur to you that the Internet community understood this to be the case long before big mail receivers and ESPs existed? You might wish to google Gary Thuerk, for example. On May 3, 1978, when he sent the first spam ever, you were all of minus nine years old, weren’t you. 🙂

So cut out the paranoia, it got old long before you had even got into the business.

March 2016 in Spamtraps: ESPs and Social Networks

ESP mail seen in spamtraps March 2016

Coming in a little late this month. The percentage of ESP sent mail vs all mail seen in the spamtraps is only 0.6% this month; it has to do both with seeing less ESP mail (about 80% of last month’s figures), and a huge increase in botnet spam. Technically, this is a top 11 list this month because Topica and Oracle Marketing Cloud managed to match spam counts so closely that a comparison would be meaningless.

Capital One: Poster Boy for Poor Security and Privacy

Capital One, a large US-based bank and credit card issuer, stands out for sending by far the largest number of transactional emails containing personally identifying information (PII) to my spamtrap collection. :/ Capital One uses a number of ESPs, but its transactional emails are usually sent from Bigfoot Interactive, owned by Epsilon Interactive.

February 2016 in Spamtraps: ESPs
(And a word about some social networks)

Do remember to read this ’til the bitter end… it’s a tad longer than usual.

Let’s start the post that includes spam from MAAWG 36 week (hi y’all! great catching up with you!) with the standard stuff. Somewhere during the latter part of the month, we collated all of Oracle Marketing Cloud into one; no more separate Responsys, Eloqua and RightNow. Having said that, the contributions from the latter two are so small as to be practically meaningless.

The percentage of ESP sent mail vs all mail seen in the spamtraps is 1.5% this month.

Penton Media: Spamming a Scraped Contact Email Address

Penton Media, a marketing firm with a past history of sending opt-out bulk email (spam), is emailing bulk advertisements to the contact email address for my personal blog ( The ESP is the Oracle Marketing Cloud, which is the combination of former ESPs Eloqua and Responsys, both of which Oracle now owns.
