How is it working as supposed to if it's not stoping spam and has broken captcha on the website? No, it seems like it's relatively random which IP is used to send an email. Most are used at the same time. You can check the volume Reputation Lookup || Cisco Talos Intelligence Group - Comprehensive Threat Intelligence FYI right now it seems like most ip's are unblocked but I guess it's a matter of time until one gets blocked and it's just going to be annoying for the users.

The problem is that the theoretical spammer isn't bound to the IP that gets blocked, Microsoft randomly uses most of them, even if you block one IP, the next email will go through the next one etc. and when that one gets blocked the 1st one might be unblocked already. For a spammer that just sends out stuff non stop and doesn't care that much if it arrives the 1st time this isn't that big of an issue. For a normal user unfortunately it is, not just the one sending but the receiver waiting for a legitimate email as well. I agree that this is Microsoft's fault but there has to be a saner way to deal with it. Unfortunately the issue is persisting, today I had another user complain about this. And the spamcop captcha is still broken...

I'm not saying it's an issue with spamcop - just that it should be unblocked anyway, banning whole IP range of a huge service because there's a spammer is an overkill. We can't report it to Microsoft because we don't know anything about what sender is the spammer, that's something that only spamcop knows, so this is the only place we can write to do something about it.

Hello, Our company uses microsoft exchange online and lately a lot of our customers are bouncing our emails due to spamcop blacklist. I've tried disputing it through the standard form but the captcha is broken, I tried multiple browsers. The IP is 40.107.8.93 (40.107.8.93 IP Address Details - IPinfo.io) . If there was spam coming from the IP please report it to Microsoft instead of blocking a huge service. The issue seems to be going on for a few days/week already. EDIT: I've checked what users sent me and there were other IP's previously but it keeps happening. January 8th - 40.107.21.135 January 4th - 40.107.21.106 December 19th - 2603:10a6:150:149::16 though this I'm not 100% 2nd Edit: Just got info another address got blocked 40.107.6.114
