Gmail pilots new FBL

Yes, it’s true. Gmail announced last Thursday at M3AAWG that they were piloting a new Feedback loop.
The Gmail FBL is currently for ESPs only. The announcement during MAAWG was that only MAAWG ESP members were eligible. They are requiring a DKIM signature for the FBL, but ESPs using individual customer d= values can get a FBL based on IPs. They are also not providing ANY information that reveals the complainer. Gmail’s intention is only to give ESPs feedback so that ESPs can prevent abuse. They are not giving feedback so complainers can be removed.
The email has a .csv attachment that has 3 columns: date, identifier and complaint rate.
The identifier is an ESP provided customer identifier. One of the ESPs I talked to said they were adding an X-header into their emails.
I’ve heard from beta testers that there is a minimum of 100 complaints before you’ll get any report.
Reports are sent daily if there is sufficient traffic to trigger them.
If you’re a MAAWG member, check the senders list for the signup URL.

Brian Krebs wins the Mary Litynski award

A little late, but I’ve been in sessions most of today. M3AAWG announced this morning that Brian Krebs won the 2014 Mary Litynski award. This award is given to people who work tirelessly to make the internet a better place.
I first had the pleasure of listening to Brian give the keynote address at a MAAWG conference many years ago. His ability to infiltrate some major spam operations and online forums for criminals is amazing. He’s also had retaliation attempts, including being SWATed and having heroin delivered to his house.
If you get a chance to hear Brian speak, I strongly encourage you to do so. His knowledge is outstanding and his speaking style is entertaining. I’ve learned a lot from Brian over the years and I’m pleased he won this award and that M3AAWG recognized his contribution to stopping abuse online.

This was a great MAAWG conference and there are a couple sessions I can write about. There were multiple sessions where representatives from various blocking groups and ISPs talked about what they block on. I have extensive notes and will be writing things up in the next few days.
