Not that this matters much, as the chance to get an IP address delisted is pretty slim anyway. I've completely given up to try to get my personal mail server delisted, as I can't even get Microsoft to tell me why they blacklisted it in the first place. Instead I'm nowadays just rejecting all incoming emails originating from Microsoft with a message telling the sender to use another non-Microsoft email account. It's just stupid. I never had problems with any other mail provider, but trouble with Microsoft as long as I can think of.
