** addresses. The routines in sbr/addrsbr.c associate semantics with those
** addresses.
**
-** If #ifdef DUMB is in effect, a full 822-style parser is called
-** for syntax recongition. This breaks each address into its components.
-** Note however that no semantics are assumed about the parts or their
-** totality. This means that implicit hostnames aren't made explicit,
-** and explicit hostnames aren't expanded to their "official" represenations.
-**
-** If DUMB is not in effect, then this module does some
-** high-level thinking about what the addresses are.
-**
-** 1. for MMDF systems:
-**
-** string%<uucp>@<local> -> string
-**
-** 2. for non-MMDF systems:
-**
-** string@host.<uucp> -> host!string
-**
-** 3. for any system, an address interpreted relative to the local host:
-**
-** string@<uucp> -> string
-**
-** For cases (1) and (3) above, the leftmost host is extracted. If it's not
-** present, the local host is used. If the tests above fail, the address is
-** considered to be a real 822-style address.
-**
-** If an explicit host is not present, then MH checks for a bang to indicate
-** an explicit UUCP-style address. If so, this is noted. If not, the host is
-** defaulted, typically to the local host. The lack of an explict host is
-** also noted.
-**
-** If an explicit 822-style host is present, then MH checks to see if it
-** can expand this to the official name for the host. If the hostname is
-** unknown, the address is so typed.
+** A full 822-style parser is called for syntax recongition. This breaks
+** each address into its components. Note however that no semantics are

+** hostnames aren't made explicit, and explicit hostnames aren't expanded
+** to their "official" represenations.
**
** To summarize, when we're all done, here's what MH knows about the address:
-**
-** DUMB - type: local, uucp, or network
-** host: not locally defaulted, not explicitly expanded
-** everything else
-**
-** other - type: local, uucp, network, unknown
-** everything else
+** type: local or network
+** host: not locally defaulted, not explicitly expanded
+** everything else
