(DEFINE THIS IF DOMAINS ARE USED) # **WARNING** # When domain names are used, SMTP transactions utilize the # full domain (official) name of the host. All host names with # no domains (abbreviated) are expanded with the local domain # by the mail service. This is consistent with Internet text standards. # All hosts sending or RECEIVING mail must recognize their official # host names. When using domains enter the official host name in # /etc/hosts and be certain that all network name servers recognize # official host names. # # ====> NOTE <==== # In compliance with rfc1123, "Received:" lines should contain a domain # literal. This will occur if the official hostname contains the full domain # when set with the 'hostname' command or the host and domain name macros # are set accordingly and the hostname contains the full domain in # /etc/hosts or the nameserver. # # Define the D macro to be the whole domain for the local host. # This configuration file supports four part domains. It can be expanded # to support n part domains.

This is # # also sometimes called "canonicalization", but has to do not with the syntax # # of the address but with obtaining the correct domain name for the address. # # # # No stripping of local domains is done for route addresses: Rulesets which # # require this must do it themselves by iteratively stripping LOCAL or # # LOCAL.D and recalling this ruleset to canonicalize the next host.item. # # # # The term "localization" refers to determining whether the next host item # # is really a reference to the current host.

This is not strictly a necessary restric- # # tion, but it simplifies the network concept and also makes for simpler # # rewrite rules.

No precedence between @,!,:: or /C= is assumed. The # address a!b@c will resolve to the uucp mailer for the remote host # 'a'. This permits the resolution of very complex route based # addresses such as; @a:@b:c!d!e::user, a!@b:c!user, a!@b.uucp:user@c. # Return addresses on mail to/from uucp or DECnet machines are also correct. # X400 addresses are detected by a leading "/C=" and are passed intact to # the X400 mailer. The address /C=US/ADMD=ptt/PRMD=pco/DD=b!user resolves # to the X400 mailer. The recipient sendmail sees b!user and routes to # the uucp mailer.

However, when a header is being # processed, S3 will have been used. The difference arises from the fact # that S3 generates the LOCAL tag, whereas the user part of a UUCP address # may contain the current host name as the first target.
