Hi Phil,

when I try

     exim -bt test@110.1.1.1


I get

    R: smarthost for test@110.1.1.1
    test@110.1.1.1
      router = smarthost, transport = remote_smtp_smarthost
      host x.x.x.x [x.x.x.x]


(the server is intended as a filter in front of our main mail server)

Thanks for your help!

Nico
