My Linode-hosted qmailtoaster install was blocked by MSN (Hotmail/Outlook/Live) recently.
However, it seems that they had singled out just my IP. I don't know why; logs showed that users on my servers had sent a total of around 600 messages to about 25 distinct Hotmail etc. users in the previous year, all personal messages from individual users. Not exactly an unstoppable spam flood. I jumped through the de-listing hoops, and they restored access after about 2 days. Linode as a whole doesn't seem to be blocked -- my IP is still acceptable to MSN -- but you might be in a netblock that MSN have decided to block, presumably because some bad actors have set up shop there. You could reach out to Linode for help. It's possible that they could either: a. Ask MSN to lift the block, or b. Allocate you a different IP or help you move to another instance. If they can't or won't, you could consider recreating your installation in a different Linode region and hope that that netblock isn't blocked as well. The risk there is that you go to all the effort of moving and then find that your new home is blacklisted as well. I guess if that doesn't work, there's always Digital Ocean or Vultr. The power of large companies like MSN to cause problems for the little guys by introducing arbitrary bans is very frustrating. I understand why they have to do it, and MSN certainly seem to be more responsive and easier to appeal to than others ... but never knowing when you'll find yourself blocked for mysterious reasons from one day to the next is annoying.
