I run many domains off of this machine - does it have to have a reverse pointer that matches the domain name for every domain
Only one PTR record per ip. Applications don't know how to handle more than one.
, or will it suffice to have a single correct reverse pointer?
yes.
Right now, the reverse zone for the ip that was rejected is delegated to rackspace NS, not yours.
