Let's say you are east.company.com and you also host MX records for west.company.com and so forth. If west.company.com was compromised and get blacklisted, can they potentially get the root domain company.com blacklisted? I'm thinking each domain is autonomous and only the individual domains would get blacklisted and not the entire root. Anybody know for certain? Thanks.
