Dear all,

I don't seem to be able to configure sendmail to do what I want:

We have a sun which we would like to act as a site mail hub.  We would like  it
to  recognise its own address as SCP.AC.UK.  We would also like it to recognise
its own name as ASH.SCP.AC.UK.  We have some local hosts  on  ethernet  but  we
also have two hosts which can only be reached on X25.


                             JANET
                               |
       vmt.scp.ac.uk-----x25---|----x25------- lib.scp.ac.uk
                               |
                              x25
                               |
                         ash.scp.ac.uk
                           (gateway)
                               |
                        --------------
                        |            |
                   ether-hosts  ether-hosts


So far, we seem to have mail to  SCP.AC.UK  and  ASH.SCP.AC.UK  and  our  local
ethernet  hosts  working  fine.  The problem is in getting ASH to relay mail to
the X.25 hosts via JANET.

Using the -bt test option, sendmail rejects mail to LIB.SCP.AC.UK (an X25  only
host)  with  "local  domain unknown" since it is not in the ether channel file.
If we remove SCP.AC.UK from the local channel file, then all  our  local  hosts
(both  ether  and  X25) seem to be accessible, but the hub no longer recognises
itself as SCP.AC.UK, and attempts to forward such mail to the janet channel.

Is there a way around  this,  or  am  I  attempting  to  combine  two  mutually
exclusive options?

One further problem:

We kept getting problems with addresses being expanded when they should not  :-
eg  UK.AC.NRS was expanded to UK.AC.NRS.AC.UK.  This problem did not occur when
we used the example tables provided in the  package  (glasgow's  tables).   The
crucial line seems to be

uk   ean-relay.ac.uk

in the top.dom file.  When I added this line to our tables,  the  problem  went
away,  and  UK.AC.NRS  was  not  expanded  to  UK.AC.NRS.AC.UK.   However,  the
ean-relay does not seem to appear in the final fqdn.  Why is line necessary  if
the relay is not used?

Please reply direct - I'm not on the list.
Thanks, Roderick Douglas / Dave Haywood.
