The inverse ruleset is S4. # # This ruleset is applied first to any external address before other # # rewriting is done. # # # # This concept of canonicalization is to be distinguished from usage # # of the nameserver in the $[/$] construct inside the RHS of rewrite # # rules. 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. Localization # # assumes that local UUCP host names are in class w. This is not # # strictly a necessary restriction, but it simplifies the network # # concept and also makes for simpler rewrite rules. This ruleset # # replaces explicit instances of local host with the internally # # recognized tag "LOCAL" or "LOCAL.D". # # # # Addresses which do not specify a host name for routing or domain # # will NOT have any reference to the local host appended in any way. # # # ######################################################################## S3 # # Basic textual canonicalization -- note RFC733 heuristic here. # This strips off everything but the innermost list between <>'s. # Some addresses are of the format: Full Name <address> # R$*<$*<$*<$+>$*>$*>$* $4 3-level <> nesting R$*<$*<$+>$*>$* $3 2-level <> nesting R$*<$+>$* $2 basic RFC821/822 parsing # # Turn an "at" token into "@". # # The I macro specifies space or some equivalent char defined by the OI # config option above. # R$+ at $+ $:$1@$2 "at" -> "@" for RFC 822 # Change a%b to a@b.
