[net.mail] Dangerous Path Optimizations -- WARNING!!

The recent discussions concerning path-optimization have been a bit 
disturbing since I feel such attempts at optimization could 
result in some very nasty problems due to duplication in the node 
name space. Builders and users of path-optimizers should be aware 
that no optimization of any path which is on the "FAR" side of 
the node pair "!decwrl!rhea" should be attempted. Any node 
reached via that node pair is part of the Digital Enet. This 
would, of course, not be so much of a concern if it were'nt for 
the fact that there are a number of node names on the DEC-Enet 
which are duplicates of those on the USENET. The following is a 
list of such duplicates compiled by Mark Hornton:

	apollo cadvax caesar comet  decwrl deimos
	dice   druid  duke   eagle  elsie  felix 
	gamma  gummo  harpo  ist    mordor moria 
	opus   orc    orion  parsec rabbit rocky2 
	solar  spanky taurus turing varian vaxine 
	vortex zeppo  zeus 

Please be careful when doing path optimizations! If nothing else, 
be wary of any path which includes the "!decwrl!rhea" node pair!!
