jwolpiuk Posted January 15 Posted January 15 (edited) 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 Edited January 15 by jwolpiuk Wanted to show it's an ongoing issue Quote
Engin Acar Posted January 15 Posted January 15 Hi, We are getting the same problem with the emails from almost all our suppliers. This is the failmessage; "JunkMail rejected - mail-vi1eur04on2113.outbound.protection.outlook.com (EUR04-VI1-obe.outbound.protection.outlook.com) [40.107.8.113]:13093 is in an RBL: Blocked - see https://www.spamcop.net/bl.shtml?40.107.8.113" Almost all the ip adresses which begins with 40.107.XXX.XXX ends up in Junk mail. This should be fixed ASAP. Quote

jwolpiuk Posted January 16 Author Posted January 16 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.

petzl Posted January 16 Posted January 16 (edited) SpamCop block list only blocks a single IP when it hits a span threshold algorithm ratioed to the volume of email going through that IP. Then releases it when the spam stops for 24 hours, 40.107.8.113 is not presently listed so the flood of spam going though it has presently stopped it's spam flood. The range of IP's listed may not be blocked but may have been. For a Microsoft email IP to be blocked would be very high well above the ratio for most IP's! A lot of other big email providers just block rouge IP's and don't supply figures for doing so. SpamCop Block releases IP when spam attacks stop. Microsoft IMO do not seem to of worked out how to stop spammers. Gmail is pretty good at doing this. Edited January 16 by petzl Quote
jwolpiuk Posted January 17 Author Posted January 17 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... Quote
Russell L Posted January 17 Posted January 17 The ONLY problem here is that Microsoft is not stopping the abuse of their mail servers to send spam. Take your issue up with Microsoft. Spamcop is working exactly as it is supposed to. Only Microsoft can fix this. Quote
gnarlymarley Posted January 17 Posted January 17 (edited) Wow, they finally got blocked. One thing to note is that Microsoft was warned numerous times before their inaction allowed the IP to show up on the blocklist. I have been getting abuse from their IP with a few messages a day from a .shop address trying to immitate some paypal links. Edited January 17 by gnarlymarley Quote

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.

Lking Posted January 18 Posted January 18 As a reminder the function of any block list, SCBL included, is to assist users of a block list segregating unwanted commercial email from their other incoming email. No block list provider, including SC, has the authority to stop a spammer or block spam at its source. In addition to the block list, SC uses the header of the reported email, and spam traps to identify the ISP used by the spammer and notifies the ISP that their assets are being used to spread spam. It is up to the ISP to take whatever action they deem appropriate. Unfortunately, some ISPs are more concerned about their paying customers senders of email (including spam), than they are concerned about the overall state of the internet. One common result of this $$$ mindset is to shift their clients away from IP that are blocked so the customer's emails will get through. In this day and time it is hard to realize that the internet email system was designed in a time when "all" internet users were "good members of the community" and expected to act accordingly. I'm guessing that lasted about 26 minutes. Block lists are one answer to that design shortcoming. IMHO to redesign the email system now would be similar to changing the U.S. electrical grid. Somethings may continue to work. Most would not. The result for those trying to receive email is to work with their incoming ISP and/or use some app to help filter their incoming email. Currently there are 80+ email I have filtered into a trash folder waiting for me to report them. The result for those trying to send email is to use an ISP that will provide them a fixed IP that no other user can used to send spam, OR use an ISP that does not allow their paying customer to send spam. Either approach should result in an outgoing IP that will not be on a block list. (assuming your email lists are double-op-in lists.) Quote

That's not its only purpose, though trust me, it most definitely is stopping spam. Spamcop simply lists IP addresses that are actively sending spam, that's it, and it's working perfectly in that regard. I, personally don't wish to receive mail from systems actively being abused to send spam. Whether I choose to block communications from them, or just add a warning to an email is up to me. If you don't want to be impacted by such abusive behavior while sending mail, you can always choose not to put your email on a service that is abused without regard for the rest of the Internet.

ninth Posted January 19 Posted January 19 It is more difficult to navigate the worldwide network to run a business when time is money and every missed email is a missed opportunity for a sale. A business email address phone number is on the website and cannot be hidden from spammers profile databases or worse. It's never been so important to keep up to date with upgrades and fixes or your system becomes vulnerable to hackers...avoid skimping on free services or install the new server using wiki. I know of at least 3 blocklist crooks profiting from charging for the removal of IP addresses. Quote

Not had a problem with a SpamCop Captcha yet, but others have reported same? There have been fixes given but can't recall what? You not using a dodgy IP by any chance? I know Google will do a BOT check on one sometimes for their Captcha. Send yourself say 19 minutes apart. Then see if the IP's match? If they don't it means Microsoft are IP hopping to avoid SpamCop's blocklists spam threshold algorithm ratioed to the volume of email going through that IP. Actually I don't often get Microsoft spam, but when it does start it's in the hundreds! I report everyone. As Gmail will turn off your email account if it is DOS attacked by too much spam! Gmail don't use SpamCop's Blocklist. But possibly just bit-bin spam sending IP's. I report all spam, also at a click of a Phishing button which may activate a bit-bin dump (if they have one)?

olddog55 Posted January 21 Posted January 21 (edited) 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 & 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.

AWS03 Posted January 22 Posted January 22 We're removing spamcop.net from our real time block lists for the time being, which is unfortunate. It's been nearly a month, and there's just too much legitimate email coming from Microsoft servers that's being blocked. Hopefully Microsoft can get a handle on this, but that I know of spamcop is one of the only ones that's flagging Microsoft for spam currently. Quote

Admin Posted January 25 Posted January 25 Our company continues to be damaged by this issue. Blocking entire Mail Server IPs as a means to combat spam is like hammering in a push pin. While I acknowledge the importance of addressing spam-related issues, it's crucial to consider the broader implications of such actions. Currently, Spamcop appears to be the sole service employing this approach, and it's evident that this practice can lead to more than just a disruption in email communication. It has the potential to harm a company's reputation and brand image. I wonder if there might be a point in the future where such actions could lead to legal repercussions, including the possibility of class-action lawsuits. It's important to address these concerns as they have the potential to impact not only email senders but also recipients and businesses as a whole. Let's find solutions that effectively combat spam while minimizing unintended consequences. Quote

SpamCop members have no control over its blocklist, this is used only by ISP's that choose to use it You don't have a dedicated IP (ask Microsoft to see what's the deal)? Assuming you are not part of the problem (not using a double opt-in email list) You should be OK if you don't. Do this. Seems you are using a Microsoft shared IP, the main reason they keep getting block by spamtrap hits which are fictitious email addresses, which are scrapped by bots from websites where these addresses are put there as a poison. Spammers buy blocks of non-validated email addresses to do exactly that (end up in many spamtraps) For a Microsoft IP to end up on SpamCop's conservative spamtrap is beyond belief, it would require hits in the million a minute score? You suggesting we should swallow this spam with no defense? If I get spam I do my utmost to send spammers to court, I have had numerous successes! Edited January 26 by petzl Quote

Good point and now I noticed it in some recently posted links in both the company name and username up to 41 randomly generated chars. Would be used to stop efforts to block email addresses and makes it faster to send out maillists on mass by fraudsters. Another good reason to report these discrepancies to bill. Quote
