Using smail 3.1 on an Esix (sysvr3) system, is there a way to alias a hostname? My situation is this: I have two uucp links -- 'system1' and 'system2'. I have the "smart_path" entry in /usr/lib/smail/config set to "smart_path=system1". This way, any mail destined for an "unknown" system gets routed thru system1 and is resolved there for routing. I still get mail thru system2 -- and headers have 'system2.domain.com'. The uucp name of system2 is 'system2', not 'system2.domain.com'. Therefore, if I reply to a message that came IN thru system2, it gets addressed as system2.domain.com!something!something... Since 'system2.domain.com' is "uknown" to my system, the mail gets routed first to system1, then to system2 for delivery. Not effecient, espeically if system1 is unreachable. :-) How can I tell smail that system2.domain.com == system2? Should I be using pathalias to route things properly, since I now have TWO smarthosts as uucp links? Before, I just let my sole uucp smarthost take care of things ... it seems this doesn't work so well now. Looking for suggestions, etc from knowledgable net.people. Thanks in advance!

Yes, that's one of the main reasons for using it on a uucp based machine. >I still get mail thru system2 -- and headers have 'system2.domain.com'. >The uucp name of system2 is 'system2', not 'system2.domain.com'.

Actually, it's pretty strange for system2 to be putting it's domain name into things passing through it. It should put it's uucp name in the uucp From_ line and leave the header lines alone, except for mail originating there which should have it's domain name in the From: header line. But - it doesn't matter. >How can I tell smail that system2.domain.com == system2? >Should I be using pathalias to route things properly, since I now >have TWO smarthosts as uucp links? Before, I just let my sole uucp >smarthost take care of things ... it seems this doesn't work so well now. Just hand-build a paths file to cover the things you don't want to send to the smart-host, and all the possible alternative names for them. Specifically in this case, you need: system2.domain.com system2!%s which will cause anything addressed with the next hop as system2.domain.com to be sent by uucp to system2. I like to include all the neighboring uucp sites in the paths file as well since it saves running "uuname" to find them for each piece of mail. Maintaining a full uucp paths file might work a little more efficiently since it could choose the best starting point towards any address for you, but it may not be worth the trouble.
