Hi all,
Chasing someone that can help with an ongoing issue. One of our mail servers
are unable to send to any Microsoft Hotmail or live users.
Have been through the SNDS process and says that all IP's are ok and that
errors are unlikely.
It appears to be relating to a specific /24 range. However, I can't find any
issues that would be causing the mail to be rejected.
Below is the error being received back from Microsoft mail servers.
host
apc.olc.protection.outlook.com[104.47.124.33]
said: 550 5.7.1 Unfortunately, messages from [xxx.xxx.xxx.xxx] weren't sent.
Please contact your Internet service provider since part of their network
is on our block list (AS3150). You can also refer your provider to
