We also get more FBL from microsoft than Yahoo but this also because FBL from Yahoo decreased in the last 5 months. On the same date (Nov, 28th) we stopped seeing the "Sample HELO" and "Sample MAIL FROM" column contents in SNDS web. > Here's a 6-months line, it's pretty obvious (sorry for the folks in text > only): > [...] > I can't say if it's "back to normal" as it's too soon to say if it's > stabilized or if it will still grow.

I can confirm an increase in FBL reports from Microsoft and now we are back to last February rates (in march FBL rates dropped a lot for us). I'm convinced, too, that this is not an increase in user spam reports, but simply an increase in "forwarding" existing spam reports from Microsoft. Maybe they fixed a bug with FBL forwarding or they changed their policy about that. > However SNDS still isn't providing anything more, I couldn't spot a single IP > with more than 0.1% of complaints. I'm not sure if it's because despite the > increase of FBL, the real complaint rate still is lower than 0.1%, or if SNDS > isn't providing the right count. We usually get much less than 0.1% complaints so the "<0.1%" may be correct. We have some IP with very low volumes (less than messages per day) with higher complaint rates and from a first review the rate could match the number of FBL we received (e.g, an IP with 200 messages sent and 0.5% rate in FBL had 1 FBL sent to us, another IP with 500 email and 0.2% rate in FBL had 1 FBL sent to us for that day).. In the past 6 months I could never do this "match" as I often could not find FBL for IPs with higher abuse rates. So, maybe something have been fixed: let's hope the fix is here to stay!
