On: Microsoft no longer signs Windows drivers for Process Hacker

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.

At least you got a response! Most people don't. According to some previous blogposts and threads on this topic, apparently if you just contact them often enough, they will after a few months escalate the problem to the competent team and get you unblocked.

Yes, I've done this successfully several times. It usually takes several tries though.
