"You need to tell your customers that have your free to spammers Microsoft 365 throwaway account IP's getting blocked , for the receiving ISP to stop using the SpamCop Block list" That's a ridiculous statement. Why? Because those of us that are having this issue, of inbound emails that are legitimate from O365, we are not complaining about "Free Throwaway Account Users", but longtime, legitimate O365 corporate users. Many of the emails being blocked, are coming from multi-billion dollar clients and partners of mine, that have thousands, and even tens of thousands of O365 email users/accounts under their domain. They are the ones being blocked by SpamCop because they block entire IPs and subnets, not individual spam emails. I use a product called spam Reader that integrates with my Outlook and filters spam. It does a great job. 99% efficient. It does, once in a while, filter out a legitimate email. But guess what? I can review the spam folder contents, find that email and unblock it. With SpamCop, I have no such ability. It either all or nothing.

Punish the innocent for the actions of the guilty Blocking entire IPs, or subsets of IPs, or ranges of IPs, such as O365 outbound SMTP servers that have a high volume of spam, is not stopping the spam, it's only blocking legitimate emails from those IPs from getting to their legitimate intended recipients. It's akin to my mailman not delivery any of my mail because one of the items is a marketing insert. It's the same as having everyone taking their shoes off at the airport because some idiot 20 years ago tried to use his shoes for something other than their intended purpose. Bulk blocking is not the answer here. Block the emails themselves that are spam, provide the recipient the ability to review said spam, and decided for themselves if it's spam or not. My business is losing thousands of dollars a day by legitimate emails being blocked without recourse to recover those emails. My partners and clients, many use O365, and their email coming into my business are bouncing back because my hosting company uses SpamCop. I've asked, multiple times to be removed from SpamCop, but to no avail. I now have to spend more money to most likely move my email to O365 itself to ensure I don't miss getting emails and possibly legal services to recover what I've lost. Maybe SpamCop is owned by Microsoft and this is a ploy to drum up more O365 customers? Very possible in this crooked world we live in today. My 2 cents worth. Be glad I didn't type out my 10 cents worth.
