Continuous spams from similar sources

Several apparently commercial websites are sending me a lot of emails (which end up in my spam folder) having mostly to do with health matters and equipment plus others such as knives. I know I can continue to trash them every day, but it irks me to know that they are sending me unsolicited product ads that I have no interest in. By the way, I've never opened any of these emails. Here's what they look like: Subject: Nuubu Detox Foot Patches Address: [Edited: "Personal Information"]icrosoft.com All of these problematic email's addresses end with .onmicrosoft.com I've tried using the email Filters option but I've not been successful. I would appreciate any suggestions to solve this problem.

Thank You,

Bob [Edited: "Personal Information"]

This link might be of help to you: https://msrc.microsoft.com/report/abuse

Other than that, there's very little recourse.

Thank you jweaver0312. Microsoft states that they will not solve problems with spam. I've never opened one of those spams to see if I can tell the website involved with these spams to remove my email address from their data base.

Unfortunately there isn't much that can be done. It might have an unsubscribe list, but I wouldn't touch it honestly.

To explain that a bit more, Microsoft allows for trials of their business grade services. The somename.onmicrosoft.com domain is the default one given with sign up. While most use it for good purposes for their actual business or whatever personal reason that they're using business grade services for, the easy methods of sign ups, even for trials, opens the room for those using it for not so good purposes. Unfortunately they are not held to the same standard of outbound spam as compared to personal email accounts.

@bojoze Might not even be microsoft or one of their affiliates. From running mail servers for quite some time, and even to this day, I can tell you the majority of the spam is coming from compromised cloud servers, cloud server services that deliberately allow spamming, and otherwise poor reputation sources. If they hit an email address that works, you'll get 20+ per day. Very annoying.

Unsubscribe links? All that does is confirm your email address. Don't be doing that. Then you'll be on every list on the planet.

If you dig into the email headers (view source) and see where they came from, it's not the domain name you should be looking at, that's easily spoofed. Look up the IP address where it came from, and who owns that block of IP addresses. The same companies pop up more often than not.

If you run your own mail server and run the firewall, the fix is easy. I just don't allow traffic of ANY kind from several companies or any of the IP ranges they use. You can't block CDIR ranges on Xfinity to stop it, and that's what you'd have to do.

There isn't much you can do about it, other than report it (to Xfinity, not who sent it) and then perhaps Xfinity will ban the offending networks like I do eventually.

I have not received any .onmicrosoft.com spam mail for several days. I believe that XFinity listened to me and did something about it. I hope this change for the good lasts. Thanks for your replies, everyone.
