What I have is a small network of 5 machines which I would like to direct mail to a mail router. The mail router (or smart-host) needs to use SMTP to talk to the local network, and UUCP for everything else. Also, the mail router will sometimes be connected to the internet (which is what motivated the DNS work), so it would be nice if the router could deliver things via the internet "when it could", as you suggest above. So, when I installed the new version of sendmail, and I sent mail on one of the interiour nodes - I discovered that no matter what I did, the interiour node always queued the mail it was to send to the router, waiting on DNS. The only way I found to fix it (I believe now we have determined others) was to rebuild sendmail with DNS look-ups disabled. Prior to this version of sendmail, the absence of the 'I' option caused it to not use DNS. I'm continuing to look into exactly how to set this up... - Dave Rivers - p.s. As an aside - my account says "Thomas David Rivers" - but it's a Southern U.S. tradition to use your middle name, please call me "Dave" :-) Now, your first question should be "Why did that fool put his entire name in the gecos field if he wants us to call him 'Dave'?" Good question! It goes back to the legal issues, problems with banks, etc... so, I always use my full name in anything remotely "official."
