Ah, yes: Hello, My name is [Kumar/Numan/Punith/Suresh/Sachin] and I work with the Outlook.com Sender Support Team. I do not see anything offhand for the IP (xx.xx.xx.xx) that would be preventing your mail from reaching our customers. Good bye and fuck off. In response to complaining that their servers say - 550 5.7.1 Unfortunately, messages from [xx.xx.xx.xx] weren't sent. Please contact your Internet service provider since part of their network is on our block list (S3150). Completely and utterly ridiculous.
