The  setting  up  rDNS  on  the one server would only be for that local
server.   All   other  servers that are not using the one local server
for  DNS resolution would look to your provider. You would either have
to 1) get your provider to delegate rDNS to you, 2) duplicate the rDNS
setup   on  the  additional  servers, or 3) point DNS (resolv.conf) to
the one server that is working locally.

Without   your   provider   delegating   rDNS to you, the "rest of the
world" would still be looking to your provider for rDNS, regardless.
