Title: I&#x27;ve had this IP for almost a decade. It&#x27;s not on spamhaus, DKIM and SPF are correct, and I&#x27;ve signed up for MS&#x27;s Junk Mail Reporting Program and Smart Network Delivery Services. They still reject my mail with<p>&gt; Unfortunately, messages from [45.55.34.226] weren&#x27;t sent. Please contact your Internet service provider since part of their network is on our block list (S3140). You can also refer your provider to http:&#x2F;&#x2F;mail.live.com&#x2F;mail&#x2F;troubleshooting.aspx#errors.<p>I went through their support channels and they were completely useless.<p>&gt; Thanks for your patience while we investigated your request.<p>&gt; Below your IP address(es) and their status(es) are listed.<p>&gt; Not qualified for mitigation<p>&gt; 45.55.34.226;<p>&gt; The IP(s) above do not qualify for mitigation.<p>&gt; Please note: This outcome indicates behavior that misses standards; please review Improving E-mail Deliverability into Windows Live white paper for helpful tips.<p>...<p>&gt; What standards are missing? DKIM and SPF are passing and I got the IP taken off of Spamhaus recently. Other email servers like gmail aren’t finding an issue.<p>...<p>&gt; Your IP (45.55.34.226) was blocked by Outlook.com because Hotmail customers have reported email from this IP as unwanted.  One possible explanation for this is the automatic forwarding of unfiltered inbound messages, including unwanted messages, to Outlook.com&#x2F;MSN addresses.<p>&gt; Please confirm that your emails comply with Hotmail’s technical standards.<p>&gt; For more detailed information about best sending practices to Outlook.com users, please review Outlook.com Enhanced Deliverability white paper.<p>...<p>&gt; I’ve ensured there is no open relay, and I’ve only tried to send messages to my own Hotmail address so far. There are no other user accounts on this email server, just me.<p>&gt; I’ve also signed up for the Junk Mail Reporting Program&#x2F;Smart Network Data Services with that domain&#x2F;IP. I don’t see any incidents there.<p>&gt; Around what day&#x2F;time was email reported as wanted?<p>...<p>&gt; Thank you for contacting the Outlook.com Deliverability Support Team.<p>&gt; As previously stated, your IP (45.55.34.226) do not qualify for mitigation at this time.  I do apologize, but I am unable to provide any details about this situation since we do not have the liberty to discuss the nature of the block.<p>&gt; At this point, I would suggest that you review and comply with Outlook.com’s technical standards.<p>&gt; We regret that we are unable to provide any additional information or assistance at this time.<p>I&#x27;ve gone through all the links they sent me and nothing is wrong with my email server. It&#x27;s impossible that I could have ever sent spam. They just decided they don&#x27;t like me for no reason and I don&#x27;t get to send them mail.
