I have a small mail server I use for my open source projects. Very little email gets send out. We also own our own /24 hosted in a Datacenter. Microsoft randomly blocks our mail server, not because of its reputation, but because there is an IP "near but outside" our /24 that has a bad reputation. I have went 15 rounds with their Support department who is clueless. When you first report it, they check your subnet and say "we are not blocking any IP in this range" and close the ticket. You then have to spend weeks going back and forth with them, until it magically starts working again (and no response as to why). Then a month later its back to being blocked.
At this point I have given up, and have actively blocked people from being able to sign up for our forums/services using a microsoft related domain, as they will never receive the registration email (thus causing more support issues for me).
To make matters worse, is over 50% of spam email incoming to our mail server originates from Microsoft servers.
