    I'm a newcomer,  and have just  installed MX 3.1c  over CMUIP 6.6. Name
completion for outgoing smtp isn't working; what am I doing wrong?

The NAMRES$CONFIG file is:

If I sit on v2.ph.ed.ac.uk and send to MX%"djc@th", it fails:

However, if I ask the DNS (via IPNCP) about th, it's OK:

----------------------------------------------------------------------------

edphv4$ ipncp
IPNCP> rr th/mx
   # of RRs = [00000005]
  MX: Pref = [0000000A] Name = [aida.ph.ed.ac.uk]
  MX: Pref = [0000000D] Name = [castle.ed.ac.uk]
  MX: Pref = [0000000E] Name = [festival.ed.ac.uk]
  MX: Pref = [00000014] Name = [nsfnet-relay.ac.uk]
  MX: Pref = [0000001E] Name = [sun2.nsfnet-relay.ac.uk]

IPNCP> rr th.ph.ed.ac.uk/mx
   # of RRs = [00000005]
  MX: Pref = [0000000A] Name = [aida.ph.ed.ac.uk]
  MX: Pref = [0000000D] Name = [castle.ed.ac.uk]
  MX: Pref = [0000000E] Name = [festival.ed.ac.uk]
  MX: Pref = [00000014] Name = [nsfnet-relay.ac.uk]
  MX: Pref = [0000001E] Name = [sun2.nsfnet-relay.ac.uk]

----------------------------------------------------------------------------

Finally, if I  send to   MX%"djc@th.ph.ed.ac.uk" it  succeeds; so it's name
completion in  MXLOOK, I suppose,  which is failing. I  tried a few things,
without  success. The doc  says it's  supposed to use the  built-in NAMRES,
which seems to work OK for IPNCP.

Help, please!!
