I've just checked our traps and we also saw a big spike in traffic from this range but has been tapering off throughout the day. Based on all the samples that I've looked at, they're all showing authenticated SMTP along with some other tell-tale signs, so maybe they've had a massive breach of

Hi Alessio, You could try our Authentication Blocklist: https://docs.abusix.com/ami-production-zones/authbl This doesn't pre-emptively list cloud IPs, it only lists IPs where we've seen evidence of compromise/abuse and these come from a variety of sources, some of them I believe to be novel

One thing that I think we can do to "help" in this instance is actually list which addresses traffic has been seen from, rather than just reporting the /64 being listed. For this range - I'm only seeing 3 IPv6 addresses hitting traps 2a01:7e01::f03c:92ff:fed4:25b5  "YourBud " - abuseable web

As the manager of a blocklist, I find myself strongly agreeing with Larry and Keith. Autoresponders are a nightmare - I see lots of brokenness every single week.   Including auto-responders with no headers that indicate the message was an automated response at all.   I had one last week that

Don't get me started on this one. I'm not aware of anyone other than zealots that use it. I can't imagine that it's useful for anything other than scoring a very small amount in something like SA/rspamd or for use in some meta/composite rules, but IMHO it's a waste of DNS lookups. It's so
