name server..... huzzah!!

Changes from Greg Couch <ucsfcgl!gregc> for V7 compatibility and
miscellaneous bug fixes; "clear" => "bzero" and "bmove" => "bcopy"
throughout for consistency; bzero is now in bcopy.c (these are
supplied by libc on 4.2bsd)

abortive attempt to install a name server.... sigh.

always fold case on host names; fold case on the LHS of aliases

disable UPPER->lower case mapping in RHS's of aliases so that upper
case letters can be used in file names and as args to programs.

change macro expansion character from $ to \001 so that $'s can be
used in headers -- the .cf file is unchanged by mapping $ to \001.
\001 is now a manifest constant.

handle dollar signs in headers properly

reset errno in parseaddr so that syserr gives a permanent error code and
no extraneous information about non-errors

4.2 release version

rewrite again with ruleset 3 after appending from domain so that we can
add any punctuation, e.g., "<" "@" "domain" ">"

Pass the delimiter character to parseaddr so that we can correctly
decide between comma and space

Handle OLDSTYLE addresses properly with the -t flag; notice that tabs also
delimit addresses (as well as spaces)

Ignore delimiters (e.g., commas) inside quotes

arrange to cleanup addresses using ruleset 4 before storing in ADDR struct

Avoid core dumps on very long addresses in headers.

implement classes and mailer flags as a bit map; define new class 'w'
as the set of all hosts we are known by

be sure everything gets appropriately externalized; canonname goes away,
since everything is now done by remotename

allow user-setable error codes in "error" mailer

split up FULLSMTP flag -- now have "X" (M_XDOT, use hidden dot algorithm),
"p" (M_FROMPATH, use reverse-path in MAIL FROM:<> command), and "L"
(M_LIMITS, enforce SMTP line limits). I would like to c

split up FULLSMTP flag -- now have "X" (M_XDOT, use hidden dot algorithm),
"p" (M_FROMPATH, use reverse-path in MAIL FROM:<> command), and "L"
(M_LIMITS, enforce SMTP line limits). I would like to change the format
of the mail defn one more time to make named fields so that it would
be more extensible.

have canonname pass the address through ruleset four also

Change parse to parseaddr for BB&N TCP/IP implementation; clean up
comments in daemon.c to simplify the poor alternate protocol type.

Fix a bug triggered when we add the sender's "@domain" to an address
in the message body that is missing a domain -- we forgot to null
terminate the list.

be able to match the inverse of a class using the $~x syntax
