Just go read here…

I wrote earlier this week about bad ways to evaluate and choose an ESP. It was all going to end today in an insightful and profound post telling all of you exactly how to find the best ESP. Then Smartinsights published an insightful and useful article on choosing an ESP yesterday. So, yeah, just go […]

I do not think that means what you think it means

Yesterday, I looked at the analysis of ESP delivery done by Mr. Geake. Today we’ll look at some of his conclusions. “Being blacklisted most likely suggests that sender IP either sends out to a great deal of unknown or angry recipients.” That’s not how most blocklists work. Most blocklists are driven by spam traps or […]

Twisting information around

One of my mailing lists was asking questions today about an increase in invitation mailings from Spotify. I’d heard about them recently, so I started digging through my mailbox to see if I’d received one of these invites. I hadn’t, but it clued me into a blog post from early this year that I hadn’t […]

How to respond to an abuse complaint

There’s a lot of variation in how ESPs respond to a report of one of their customers sending spam. Almost all ESPs will suppress future email to the recipient. Most will also note that there was a complaint about the sender, and use a count of those complaints for reporting, triage and escalation of problems. […]

When the inbox isn’t the inbox

There was a discussion today on the OI list about email filtering that brought up something I usually don’t mention in delivery discussions. Most email marketers treat the inbox as the holy grail of delivery. Everything about delivery is focused on getting to the magical inbox. I think, though, that inbox is often just shorthand […]

Robust protection under the CDA

Venkat also commented on the Holomaxx v. MS/Y! ruling. As with blocking or filtering decisions targeted at malware or spyware, complaining that the ISP was improperly filtering bulk email (spam) is likely to fall on unsympathetic ears. It would take a lot for a court to allow a bulk emailer to conduct discovery on the […]

Amendment was futile

Judge Fogel published his ruling in the two Holomaxx cases today. Defendant’s motion to dismiss having been granted, IT IS ORDERED AND ADJUDGED that Plaintiff’s complaint be dismissed without leave to amend and that the action be dismissed with prejudice. The full text of the rulings are available (Yahoo order, Microsoft order). There’s nothing very […]

Uptick in botnet spam

There’s been a heavy uptick in botnet spam over the last few days, judging by things I’m hearing and my own mailboxes. There are a few common subject lines, but all of them are trying to get recipients to either run programs or visit malicious web pages. The first subject line I’m seeing a lot […]

Defeating spamfilters through obsession

[The harasser] was hitting me on email and twitter for more than [2100 messages], and the thing was, those all got past the filters I’ve got in place. So one obsessed crazy man with minimal technical skill and nothing but persistence outperforms all the spambots out there, at least on the scale of individuals, if […]

Blocklist changes

Late last year we wrote about the many problems with SORBS. One of the results of that series of posts was a discussion between a lot of industry professionals and GFI executives. A number of problems were identified with SORBS, some that we didn’t mention on the blog. There was an open and free discussion […]

  • AOL compromise

    Lots of reports today of a security problem at AOL where accounts are sending spam, or are being spoofed in spam runs or something. Details are hazy, but there seems to be quite a bit of noise surrounding this incident. AOL hasn't provided any information as of yet as to what is going on.4 Comments


  • ReturnPath on DMARC+Yahoo

    Over at ReturnPath Christine has an excellent non-technical summary of the DMARC+Yahoo situation, along with some solid recommendations for what actions you might take to avoid the operational problems it can cause.No Comments


  • AOL problems

    Lots of people are reporting ongoing (RTR:GE) messages from AOL today.  This indicates the AOL mail servers are having problems and can't accept mail. This has nothing to do with spam, filtering or malicious email. This is simply their servers aren't functioning as well as they should be and so AOL can't accept all the mail thrown at them. These types of blocks resolve themselves. 1 Comment
