Hi ,

Thanks for your patience while we investigated your request.

Below your IP address(es) and their status(es) are listed.

Not qualified for mitigation

89.234.181.137;

These IP(s) have previously received mitigations from deliverability support, and have failed to maintain patterns within our guidelines, so they are ineligible for additional mitigation at this time.

Outlook.com limits the number of email messages a particular IP can send within a period based on the IP's reputation. When an IP exceeds its sending limit, any further SMTP commands from the IP will receive error code 421 from Outlook.com and the connection will be terminated.

Please note: This outcome indicates behavior that misses standards; please review Improving E-mail Deliverability into Windows Live<http://download.microsoft.com/download/e/3/3/e3397e7c-17a6-497d-9693-78f80be272fb/enhance_deliver.pdf> white paper for helpful tips.
