This is an unpatch version of tcpserver from the latest ucspi-0.84 and you
are correct. The tcpserver instances do go change to (in my case) sh
instances when the reverse lookups have completed. My goof and sorry for
the confusion!
Dave and John, do you both run tcpserver with the -H option set? If so,
what shows up in your Received: headers and your mail log regarding mail
receipt from outside hosts? Or are you lucky and receive most of your
mail from machines with valid reverse DNS entries? My DNS setup is NOT at
fault. :)
