I have a small problem to solve problem my problem using
UK-sendmail.

UK-sendmail Examples are made into network where gateway to the
next level is tcp box, but I can't see how to define this 
gateway as a uucp connection, but keeping internet style in
address.

I try to explain that....

         ^^^
          |
    uucp to the top level
          |
    ---------------
    |  my machine |  -----|
    ---------------       |
          |               | ethernet
      uucp                |
      to the other        |
      domains             |
      with same structure |
      eq. I am a top      |
      level for other     |
      domains             |
                          |       ---------------------
                          |-------|  other (slaves)   |  
                          |       ---------------------    
                      ----------
                      | bridge |
                      ---------
                      ||||||||||
                      ----------
                      | bridge |
                      ----------
                          |   an other ethernet
                     ----------------
                     |  other domain|
                     ----------------
                          |  gateway to the bigger
                          |   word is still 'my machine'
                            

I solve this proble by editing some default configuration
files using next example.
but how to do this same using UK-sendmail configuration files?

1) there is definition for top level domain and how to
   use it
