The latest release of Mips RISC/os 4.5 uses sendmail 5.61 and a sendmail.cf version 1.34 from Berkeley dated Jan 1989. This sendmail.cf hides non-registered hosts behind a NIC registered host when the destination is to domain .arpa. Is this still necessary? I don't see other sendmail.cf's doing this, and the README file from Berkeley said the need to do this would be going away. In addition, all mail for the csnet domain is forwarded to the csnet relay machine. Is this still necessary or does dns work to csnet? -- Pierce Cantrell Internet: cantrell@eemips.tamu.edu Department of Electrical Engineering Texas A&M University tel: (409) 845-7441 College Station, Texas 77843-3128 fax: (409) 845-6259

Is this still necessary? There aren't any .ARPA hosts any more, but this might not be a bad idea for hosts in .MIL, since many of those still do not use the domain name system and probably never will. That way, at least you'd be able to correspond with them. We STILL rewrite outgoing mail from UCSD as user%localhost@ucsd.edu because of this; there are quite a few instances where ucsd.edu being the only campus host in the NIC hosts table has prevented people from communicating unless they used this form. >In addition, all mail for the csnet domain is forwarded >to the csnet relay machine. Is this still necessary or >does dns work to csnet? I don't believe .csnet exists any more either. That's obsolete and probably can be deleted. As I recall, all csnet hosts went to real domain names a while back. Brian Kantor UCSD Network Operations UCSD C-024, La Jolla, CA 92093-0124 USA brian@ucsd.edu BRIAN@UCSD ucsd!brian

Is this still necessary or >does dns work to csnet? CSNET is all domain names, and the fake ".CSNET" domain can really truly be removed. Not an official CSNET statement, but a fact nonetheless. /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.

While it is true that hosts in the .ARPA domain are being renamed to other domains, the process is not yet complete. There are currently about 100 hosts whose primary names end with .ARPA. Almost all of these holdouts are MILNET hosts with .NAVY.MIL aliases, but I noted one or two entries in HOSTS.TXT with only .ARPA names. In addition, there are about 800 hosts with non-.ARPA primary names that maintain .ARPA aliases. To answer the original question, it should be plenty safe to remove the sendmail.cf rule that rewrites "user@subdomain.host.arpa" as "user%subdomain@host.arpa" unless you know of a specific case in which this is required (I actually benefited from the rule once when my host was named LOGICON.ARPA). :: Jeff Makey Department of Tautological Pleonasms and Superfluous Redundancies Department Disclaimer: All opinions are strictly those of the author.
