Need to find out why in motion servers can not send to any msn email properties. They all bounce back with the following message:


Status: 5.0.0


Remote-MTA: dns; outlook-com.olc.protection.outlook.com


Diagnostic-Code: smtp; 550 5.7.1 Unfortunately, messages from [74.124.217.46] weren't sent. Please contact your Internet service provider since part of their network is on our block list (AS3140). You can also refer your provider to

Hello Christylane,

Sorry for the issues for not being able to send email to an MSN server. This is typically the result of a server being blacklisted. You can follow the directions in this tutorial for de-listing. Once the server is delisted then you will be able to send emails to MSN again.

If you have any further questions, then please let us know.

Regards,

Arnel C.
