Good luck with that. Last time I checked, Microsoft was using NetRange: 52.96.0.0 - 52.115.255.255 and NetRange: 40.74.0.0 - 40.125.127.255. With their MTA's scattered throughout. What is really needed is for Microsoft to get rid of spammers hosted on their systems.

@Geeksultant & others: The party 'blocking' your mail is *your* email provider. Any good eMail provider will use a weighting mechanism, combing multiple blocklists that, in the preponderance of evidence, results in an 'Accept', 'Warn', or 'Block'. The 'Warning' conditional acceptance is usually by either altering the Subject line (e.g. by adding 'Possible spam') or by sending the eMail to the spam folder. It is up to each individual recipients (your) eMail provider to make this determination. For any blocked messages, you might want to check the status of your current, Microsoft/Outlook eMail MTA: https://whatismyipaddress.com/blacklist-check And, just as a point of reference, here is a count of the 11 spams I have seen in the past half-day: 2 Listed at AUTHBL.dq.spamhaus.net 2 Listed at dnsbl.dronebl.org 3 Listed at b.barracudacentral.org 3 Listed at bl.spamcop.net 3 Listed at cbl.abuseat.org 3 Listed at iadb.isipp.com 4 Listed at SBL-XBL.dq.spamhaus.net 7 Listed at bl.mailspike.net 7 Listed at dnsbl-1.uceprotect.net You will note that SpamCop is right in the middle of the hits count. So don't go blaming an individual BL provider. And that is why a good eMail provider uses multiple BL's in a weighted configuration. If it's only one hit, it's probably not true spam. But more, ???

Please read and understand the Original Post. Spamcop parses and forwards our report to the responsible ISP. Within that notification [ a message that YOU will not normally receive a copy of ] is a referral URL to https://www.spamcop.net/mky-proxies.html That is a bad link. Follow it yourself... https://www.spamcop.net/mky-proxies.html

Sorry @petzl, but this issue has nothing to do with reporting links. As pointed out by the OP, it's an in-house Cisco/Ironport/Spamcop issue. They have an old bad URL in the report they send to the ISP contacts. If you REALLY want the published reporting links (which has nothing to do with this issue.) I'd be glad to send you some. I just counted 107 in the last 10 days logs alone.

Darn. I spoke too soon. Just got another Microsoft spam from onmicrosoft.com Guess 'they' just bot another services domain. Company name 'x783qsi' Sure looks bogus to me. Came from the Microsoft protection.outlook.com MTA at 40.107.93.48 From: Dicks Sporting Goods Rewards ! <..snip..@x783qsi.onmicrosoft.com> Subject: Stanley Tumbler Exclusive Rewards For You ! Sigh.

I've been receiving MANY spam messages originating from Microsoft via their protection.outlook.com MTA's. But on a positive note, it seems to have (hopefully) been resolved. I haven't seen one since Friday, Jan 19 at 19:06:53 Many of them were using the same address as the sender AND the recipient. e.g. I'm spamming myself? [humor...] Most were originating from their 'onmicrosoft.com' services domain I've tracked all of these spams back to hacked eMail addresses that were used at various online services. ( Marshalls, Zacks, NavellierGrowth, AceHardware, etc. ) (I tend to use unique email addresses for everything.) A sampling of the Subjects: "-Re: 2nd_attempt_for MYNAME" "Celebrating Dicks Sporting Goods anniversary with an Stanley Tumbler" "Exclusive Product Awaits You: Complete Our Survey" "Get Rewarded for Your Opinion: Take Our Survey!" "Get a Dewalt LED Work Light for Your Valuable Input" "Important for MYNAME!!!!!" "Important for MYNAME" "Important_for: MYNAME" "Jumpstart Your DIY Project with a FREE Pittsburgh Tool Set!" "Message for MYNAME" "Re: Your Southwest Reward" "Shape Our Future: Survey &amp; Win Dewalt LED Work Light Prize" "Survey Time: Win Big with Our SMEG Bean to Cup Coffee Machine" "Welcome to Dewalt LED Work Light Reward Panel" And NONE of these would be considered safe to open in your email client. All have been reported to both Microsoft and SpamCop. And remember: The SpamCop Blocking list is only advisory. It is up to the recipient system as to how any flagged emails should be handled. If you're curious, one of the IP ranges used by Microsoft is: NetRange 40.74.0.0-40.125.127.255 NetName: MSFT abuse@microsoft.com And all the Microsoft sourced spam I've seen has been coming from the 40.107.xx.xx/16 network.

Ditto. Still an issue. I re-submitted this issue via https://www.spamcop.net/w3m?action=contactform on 10 January 2024. And 10 days later, still no response...
