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;

Diagnostic-Code: smtp; 550 5.7.1 Unfortunately, messages from [] 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.
