This is exactly the reason RES_DNSRCH should be turned off.  Sure you
can distinguish the systems with a trailing '.'.  How do you intend to
communicate this bit of magic to the ordinary users?  Far better to
train them to use FQDNs so that mail works as expected and they can 
learn from their mistakes.  Violating the Principle of Least Astonishment
has no pay-off with systems used by everyone in the organization.
