curt@cynic.wimsey.bc.ca (Curt Sampson) (03/10/91)
I'm bringing up Smail 2.5 on my Xenix system.
I feed several other sites, but do most of my routing though a smarthost
so I don't have to keep huge numbers of maps around.
My site is known as cynic.wimsey.bc.ca or cynic.uucp. I sometimes get
mail in for sites under me addressed to, say, gallifrey.cynic.uucp.
Unfortunately, unless I explicitly put gallifrey.cynic.uucp in my paths
file it ends up going back to my smarthost.
Is there any way to get smail 2.5 to take anything of the form
xxx.cynic.uucp or xxx.cynic.wimsey.bc.ca, try and uux it to xxx!user,
and bounce it if the system is not known to my uucp?
Is this even a good strategy to use for my mail?

Smail 3.1 can be given a list of domain names to remove before searching for a hostname so you can get this behaviour pretty much automatically. With Smail 2.5, you would probably have to maintain the exact names in your paths file. It shouldn't be too hard to merge the output of 'uuname' and your own name to produce the list you need in the paths file. >Is this even a good strategy to use for my mail? I think so. It should always be possible to route uucp mail as though x.y.z were z!y!x. Yes, I know it may be suboptimal and that's not what it is supposed to mean but once you get to a machine where this interpretation makes sense, it doesn't matter. Usually, though, you wouldn't get this kind of address unless your neighbors are putting it in their From: header lines and they shouldn't be doing that without your approval.

Somebody is sending out very illegal addresses. There is no such thing as a .UUCP domain, so there is no .UUCP registration authority, so there is no one to register cynic.uucp as a domain within .uucp. Your best bet is to bounce the mail back to the sender with a note explaining things. /r$ -- Please send comp.sources.unix-related mail to rsalz@uunet.uu.net. Use a domain-based address or give alternate paths, or you may lose out.

I did find out that .uucp is a "fake" domain, and thus cannot have subdomains. The problem was caused by one of the sites that I feed assuming otherwise and sending out stuff from user@gallifrey.cynic.uucp. I have informed him of this and fixed the problem. Incidently, I also figured out how to fix my smail problem and learned a lot about domains and internet mail in the process.
