[mailop] Microsoft mail Contact

2018-03-11 Thread Ross Gay 
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

E-mail isn't instant messaging -- don't expect instant delivery.  Yes of 
course TLS slows things down, though not by too much as long as it is 
working.

Correct.  It also means that the sender is abusive: even *attempting* to discern
when users open/read messages is clearly unethical and wholly unprofessional.
