Hi Bob
Sounds to me as though you have exactly the setup I have and suffering the same
problems with sendmail - I never managed to stop it forcing a dialup for DNS
resolution even though I had the full ampr.org DNS domain loaded on the local
DNS.
I switched to Exim which now also allows a 'psuedo hopper' facility for those
stations without MX records that are reachable locally. smtp hopper will be
familiar to *NOS users - its a kludge to relay smtp to the next station (ie
gateway) in the IP route to the desitination The effect can be duplicated in
Exim by either using an external director program or by using the new
translate_ip_address feature.
If you or anyone else is interested further, I can post some of the (smaller)
configuration files for Exim and bind to assist in their setup
