Is it possible to create a well-organized domain using smail? I've been trying to do this here, and I keep running into problems since smail seems to work well only in the .UUCP domain. Suppose you set up a domain Fnord.COM with a gateway named alpha (i.e. alpha.Fnord.COM) and a bunch of other machines. alpha.Fnord.COM has a full set of UUCP maps and does intelligent routing. How can machines inside Fnord.COM have the same names as machines in the UUCP maps without confusing the smail running on alpha? If there's both a beta.UUCP and a beta.Fnord.COM, how can smail be taught that mail to user@beta goes to user@beta.Fnord.COM, and that mail to user@beta.UUCP goes wherever the UUCP maps tell it to go? I've looked through the smail and pathalias source enough to know that either I'm missing something, or this is difficult if not impossible. Still, I need to be able to do this. Even if we changed all our system names to things that aren't in the UUCP maps, there's not guarantee that tomorrow's map distribution from Rutgers won't have a new node that duplicates an existing Fnord.COM node. We -HAVE- to be able to handle duplicate node names, or we have to register 50 new node names in the UUCP maps (mega-yuk). We're using smail 2.5. Is there anyone out there who has had luck pulling this off? Does anyone know if smail 3.* handles this any differently? If it looks like smail can't manage this, does anyone know where we can get source code for sendmail for System V? :-/ --- Tom Fitzgerald fitz@wang.com Researching the public's fear of Wang Labs ...!uunet!wang!fitz the unknown since 1953.

According to fitz@wang.UUCP (Tom Fitzgerald): >How can machines inside Fnord.COM have the same names as machines in the >UUCP maps without confusing the smail running on [the gateway]? As far as I know, there is no simple way to do what you want with Smail 2.5. Possible solution #1: Modify Smail to support multiple path files, each of which is associated with a given domain. Be sure that the "Fnord.COM" path file is searched first for unqualified hostnames. Possible solution #2: Modify Smail to qualify unqualified hostnames before doing path lookup; then if the qualified hostname isn't found, search for the original unqualified hostname. >Does anyone know if smail 3.* handles this any differently? Smail 3 supports multiple path files. -- You may redistribute this article only to those who may freely do likewise.
