Here is a problem that has been bugging me for some time.  I am really
not an expert (by ANY stretch of the imagination) on either VMS or
SunOS, but here goes:

We have a Vax 6310 running VMS v5.1-1.  It is networked (via an
Ethernet backbone) to a Sun server (Sun 4/260) running v4.0.3 of
SunOS. I can use the mail tool from SunView and successfully send mail
to the Vax (actually, to a Decnet node called 'apollo')  using the
address:
  giacobbe@apollo

The problem is in going from the Vax to the Sun.  When I try to reply
to the message, or send a new message using the address:
username@logos  (logos being the Sun machine) the Vax postmaster
always sends me a friendly message that it "never heard of host
'logos'" 

Originally, we thought the problem might have something to do with
Vaxmail defaulting to Decnet protocol instead of tcp/ip.  The people
on the Vax end suggested setting up the Sun so that it would become a
Decnet node.  

I am now running Ki Research Deknet/LAT software on the Sun machine.
If I go over to a dec terminal and type 'show nodes all' at the local
prompt (I assume this is the Dec LAT prompt) it lists all of the Vax
nodes : apollo, gemini, euhler, gauss etc,etc, INCLUDING logos !!

I can type 'connect logos' from the local prompt and connect to the
Sun machine with no problem.  HOWEVER, when I try to send good 'ol
Vaxmail to the 'node' logos using the address: logos::username  I get
an 'unknown node' message!!!

ARGHHHH!!!!  What's the deal?  If logos shows up as 'reachable' Decnet
node from the Dec LAT prompt, why the heck is it an 'unkown node' when
I try to mail something to it????

Any help would be *greatly* appreciated
