SORBS – back soon

If you’ve tried to get an address delisted from SORBS this week you’ll have found that their site is degraded, and there’s no way to request delisting. They’ve been dealing with some very nasty database / hardware problems and while they’re fixing those the externally visible SORBS services are running in a read-only mode (where […]

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 […]

SORBS Progress

A little bird tells me that GFI have resolved their primary blocking issue on SORBS problems. If all goes well I’d expect their infrastructure and policies to improve significantly over the next few months. We’ll wait and see whether the data quality begins to improve after that.

Office cat says

All work and no cat petting makes for a very cranky, and in the way, cat. Return Path has turned our recent series of blog posts about SORBS into a handy list for what people SHOULD do when they’re intending to run a blocklist. More regular posting will return next week.

GFI/SORBS – should I use them?

Act 1 • Act 2 • Intermezzo • Act 3 • Act 4 • Act 5 Management Summary, Redistributable Documents and Links In the past week we’ve demonstrated that the SORBS reputation data is riddled with mistakes, poor practices, security holes and operational problems, and that the quality of the end result is really too […]

GFI/SORBS – a DDoS Intermezzo

Act 1 • Act 2 • Intermezzo • Act 3 • Act 4 • Act 5 Management Summary, Redistributable Documents and Links I’ve been stage-managing for a production of The Nutcracker this week, so musical terminology is on my mind. In opera, the intermezzo is a comedic interlude between acts of an opera series. This […]

GFI/SORBS considered harmful

Act 1 • Act 2 • Intermezzo • Act 3 • Act 4 • Act 5 Management Summary, Redistributable Documents and Links A little over a year ago the SORBS blacklist was purchased by GFI Software.

  • Friday blogging... or lack of it

    It seems the last few Friday's I've been lax on posting. Some of that is just by Friday I'm frantically trying to complete all my client deliverables before the weekend. The rest of it is by Friday I'm just tired. Today had the added complication of watching the Trumpcare debate and following how (and how soon) it would affect my company if it passed. That's been a bit distracting, along with the other stuff I posted about yesterday. I wish everyone a great weekend.No Comments


  • Indictments in Yahoo data breach

    Today the US government unsealed an indictment against 2 Russian agents and 2 hackers for breaking into Yahoo's servers and stealing personal information. The information gathered during the hack was used to target government officials, security employees and private individuals. Email is so central to our online identity. Compromise an email account and you can get access to social media, and other accounts. Email is the key to the kingdom.No Comments


  • Blogging

    It's been a wild week here in the US. I have to admit, the current political climate is affecting my ability to blog about email. I've always said email is not life or death. And how can I focus on the minutia of deliverability when things are in such turmoil and uncertainty? There are many things I want to write about, including some resources for those of us who are struggling with the current administration and changes in the US. What we can do. What we must do.  It just takes work and focus I don't have right now.    1 Comment
