It's always been my impression that a domain is blacklisted based on
it's IP address. So if west.company.com has an independent MX record,
from a DNS standpoint there would be no association with
east.company.com and therefore no reason for the east domain to be
blacklisted.

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.
