UUCP is not the correct place to do hostname aliasing, except possibly for case sensitivity. I could not be too hard to fix the various versions of UUCP to ignore alphabetic case when checking for the hostname. Even easier would be a simple modification to uucp/uux to convert host names on input to lower case. Upper case hostnames are a real drag when "pathalias -i" is the approved technique to build routing tables. >There are several reasons for wanting this.

The mail router in use at NCR allows this. The 'next' information source is used to look up simple host names in UUCP paths. For example ncr-sd's configuration file has the line NEXTINFO sdcsvax ucsd!%s # backbone changed which re-routes mail from sdcsvax to ucsd since the functions of sdcsvax mave been replaced by ucsd. The host name ucsd is then looked up in the 'next' information source as well; it will be found in a sorted file as ucsd via-uux:ucsd!%s which routes it to the "via-uux" mailer, which then ships it via UUCP to ucsd. The line also replaces UCSD, uCsD or UCsd with ucsd, forcing ucsd to the correct alphabetic case. Other mailers may be added at the drop of a hat by just adding a few lines to the mail router configuration file. This allows multiple Message Transport Agents to be used, including PMDF, CompuServe and BSMTP. ncr-sd currently has 13 mailers defined. The most interesting one is the "nameserver" mailer, which looks up names address to the domain name SanDiego.NCR.COM using a separate program. The matching algorithm currently in use is fuzzy so mail mis-addressed to Mutt.Ostello@SanDiego.NCR.COM will still get to me. -- Matt Costello +1 619 485 2926 {ucsd,cbosgd,pyramid,nosc.ARPA}!ncr-sd!matt
