*boggle* What? Wow. No. Just no. That won't even work on a
toy home network where your ISP sets the rDNS, it definitely won't
work on a large corporate network. It only works in a trivial
environment.
If you're telling me that my internal mail servers must talk to each
other via the name pool-173-71-187-61.pitbpa.fios.verizon.net then...
well, never mind.
