NS1/sage and tao are on different netsworks, so I'm only testing connectivity thru sage <-> zen. It was both an issue within my /etc/namedb/s/* files, as well as my sendmail files in /etc/mail on both systems. I needed to list NS1.thought.org as my ^DS[smarthost] verywhere, then set up my virtusertable/.db file on NS1.thought.org. I made notes immediately as something started working; and have been refining as I learn more. This has been almost entirely a roll-my-own situation. ---Well, sendmail.org gave me a couple of clues. Over time this may be one for the Answerman column next year. And/or here on http://answerman.though.org, a virtual site not yet gone live. Nutshell: anyone can have his own private network working with complete connectivity. gary p3 19:10 <sage> [1007] !! telnet zen 25 Trying 10.0.0.249... Connected to zen.
