[mailop] Forging Feedback-Id and weird GPT FBL data

Hi, Since few days we are seeing weird FBL data in Google Postmaster Tools: spikes of FBLs with identifiers that could not be real and must be forged. No "strange" IPs outside our network and no authentication / delivery errors either. The Feedback-id header is not oversigned. I would exclude a

Re: [mailop] Microsoft FBL Increase

The very same here. Initially I was a bit concerned since Hotmail FBLs skyrocketed all of a sudden but actually they halved few months ago and this could be an adjustment. Alberto 2017-12-13 13:00 GMT+01:00 Benjamin BILLON via mailop : > Hello, > > > > Not especially on Nov.

Re: [mailop] No DKIM signing for Google GSuite Calendar Replies?

We are routing GSuite messages through our SMTPs adding our own DKIM signature but I don't see the behaviour you described. I see two DKIM signatures one with our domain and the other with google.com Regards Alberto 2017-12-08 19:37 GMT+01:00 Aaron C. de Bruyn via mailop : >

[mailop] FBL drop for Hotmail/Outlook

Hi, Is anybody else experiencing a drop in Feedback Loops from Hotmail? Since yesterday (CET time) we are receiving FBLs but 3 times fewer than what it used to be. We don't see any glitch from our side and I don't believe in a sudden spike of "relevancy" across the board :) We are not seeing any

[mailop] HB spike from Yahoo?

Hi, We are seeing a strange spike in hard bounces from Yahoo!, reported also for accounts that should work. "smtp;554 delivery error: dd This user doesn't have a yahoo.com account" Does anyone else see the same? Thanks Alberto Miscia | Head of Deliverability & Compliance | MailUp

Re: [mailop] SORBS help

I don't think that this is the best attitude for helping the email ecosystem (and I suppose this is what we all want to accomplish). I don't want to take anyone's side either because in the past I used to complain about some blacklists as well and I perfectly understand where we're coming from.

Re: [mailop] signup form abuse

This opens up for an interesting discussion. We experienced the very same issue in the past for few customers and enabling a captcha was the only viable option. The "bots" (don't really know actually) managed to complete a COI process with several free accounts. Ip ranges were different some on
