The problem is the MX record for fuckmicrosoft.com points to a.mx.rapturesecurity.com and rapturesecurity.com no longer exists. Maybe the server itself is up and running just fine but nobody will be able to send mail to anybody at fuckmicrosoft.com
Not only that, but there's no longer an A record for mail.fuckmicrosoft.com, so even if there is mail on the server for us, we can't connect to it.
Your best best is to email
[email protected] which is listed in fuckmicrosoft.com's whois record.
