Problem sending to hotmail / block list S3150
by Marco Kälin 16 Nov '21

16 Nov '21

Hi @ all Actually we have massive problems sending to private microsoft customers (hotmail.com, live.com, etc.) We offer some small smtp mailservices for our customers (smtp smarthost and also a mail encryption and sign service). The standard configuration of our outbound smtp servers is from my point of view set correctly: * Fix IP * Correct SMTP Banner, HELO, RDNS * A Records matches RDNS * SPF Records pass * Tested DKIM signed * Not on any Blacklist (checked with mxtoolbox.com) * No spam activities on this /24 ip range for at least 6 years * Sending to Microsoft Office 365 (Business Customers) works. We registred our IPs on the Microsoft Smart Network Data Service (SNDS). This only reports "All of your IPs have normal status". The MS Support "does not see anything that would preventing your mail from reaching our customers". But it's MS servers that bounce the mail... Remote Server returned '554 5.7.1 <hotmail-com.olc.protection.outlook.com #5.7.1 smtp; 550 5.7.1 Unfortunately, messages from [xx] weren't sent. Please contact your Internet service provider since part of their network is on our block list (S3150). You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. [DM6NAM04FT044.eop-NAM04.prod.protection.outlook.com] Has anyone experince with this sort of problem? thanks and great day.

Disable Recursion on Windows Server 2019
by Benoît Panizzon 01 Nov '21

01 Nov '21

Dear Community We have a customer who operates hosting and uses a Windows Server 2019 as DNS for his hosting customers and for which we occasionally receive complaints about this being an open resolver prone to DNS amplification attacks. Customers requirements: * DNS reachable from the Internet, for the domains he is authoritative for. * DNS recursion available for hosting customers in his IP range. He tells me, that he can only switch recursion on and off completely, but not restrict the ip ranges for which is shall be available. My quick search via Google, also only revealed how to turn recursion off completely on a Windows Server 2019. Hopefully some Microsoft Guru on this list, can tell, how to restrict recursive access to certain IP ranges? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

CDN: Access Denied Reference #18.cad1f557.1634833505.1903b12e
by Benoit Panizzon 26 Oct '21

26 Oct '21

Dear Colleagues We have a customer whose IP keep getting blocked by various CDN operators. If we change his IP, this solved the issue for a couple of days, then he is blocked again. Actual IP: 87.102.212.133 At the moment, this IP is being blocked by the CDN used by: klm.com nespresso.com easyjet.com I opened a case with Amazon, as this is the ones that host the easyjet.com CDN but they replied that he is blocked 'upstream' by their customer easyjet. Our customer called the Easyjet Helpdesk, but they have no clue what generates this error and sent him to is ISP :-/ We don't get any kind of complaints regarding the IP of this customer. https://multirbl.valli.org/lookup/87.102.212.133.html Two entries on blacklist I am not familiar with. One of them about an email misconfiguration? All the customer is seing on the webpage is: === snipp === Access Denied You don't have permission to access "http://www.easyjet.com/" on this server. Reference #18.57d61202.1634833697.32bab06 === snapp === Any hints on how to solve or what blocking provider is used (all pages show a very similar message with similar ID) are appreciated. PS: Yes, google is finding reports of this exact issue. None I found provided any useful hint on what causes the issue.
