Exchange Online Servers blacklisted

Hello,

 

today I noticed that some Exchange Online Servers are blacklisted on Backscatterer.

I only found these 2, but there might be more at this IP range:

 

40.107.1.100 - mail-eopbgr10100.outbound.protection.outlook.com

40.107.1.102 - mail-eopbgr10102.outbound.protection.outlook.com
