Dear François Poulain 

We have completed reviewing the IP(s) you submitted. The following
table contains the results of our investigation. 

Not qualified for mitigation
195.154.56.24; 62.210.101.106; 62.210.101.52; 
Our investigation has determined that the above IP(s) do not qualify
for mitigation.

Please ensure your emails comply with the Outlook.com policies,
practices and guidelines found here:
http://mail.live.com/mail/policies.aspx.

To have Deliverability Support investigate further, please reply to
this email with a detailed description of the problem you are having,
including specific error messages, and an agent will contact you.

More information needed
88.191.250.11; 
We were unable to identify anything on our side that would prevent your
mail from reaching Outlook.com customers.

If you are still experiencing deliverability issues, please reply to
this email with a detailed description of the problem you are having,
including specific error messages, and an agent will contact you.

If this is a new IP space, and you have not yet begun to send mail to
Outlook.com users, please reply to this email and one of our support
team members will contact you to collect more information.

Regardless of the deliverability status, Outlook.com recommends that
all senders join two free programs that provide visibility into the
Outlook.com traffic on your sending IP(s), the sending IP reputation
with Outlook.com and the Outlook.com user complaint rates. 

Junk Email Reporting program (JMRP) When an Outlook.com user marks an
email as "junk", senders enrolled in this program get a copy of the
mail forwarded to the email address of their choice. It allows senders
to see which mails are being marked as junk and to identify mail
traffic you did not intend to send. To join, please visit 

https://sendersupport.olc.protection.outlook.com/snds/JMRP.aspx

Smart Network Data Services program (SNDS). This program allows you to
monitor the ‘health’ and reputation of your registered IPs by providing
data about traffic such as mail volume and complaint rates seen
originating from your IPs. To register, please visit
http://postmaster.live.com/snds/. 

There is no silver bullet to maintaining or improving good IP
reputation, but these programs help you proactively manage your email
eco-system to help better ensure deliverability to Outlook.com users. 

Thank you, 

Outlook.com Deliverability Support
