Host not found mail.protection.outlook.com
Hi, we use MS EXCH 2k10 with Postfix frontend and there is a major issue with DNS resolution of mail.protection.outlook.com domains on Postfix servers. These servers are using BIND 9.9.5 nameservers...
Hello,
I have that issue as well with hundreds of domains. For what I found for now, this could be related to DNSSEC issue.
On my side I disabled DNSSEC client commands and this changes nothing.
When I dig myself, resolution is fine
For me that looks only postfix related...
