Don't have mail from su'ed people come from "daemon"

Fix botch of putting incorrect full names on some addresses (usually
UNIX-to-UNIX Copy)

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

More attempts at insuring that everything goes through ruleset 4

avoid core dump on return receipt processing; clean up return receipt
message.

clean up problems when QUEUE compile flag not defined; clean up hostname
code to run on non-4.1c systems; fix use of -oeq (quiet on errors) flag.

$e macro is now SMTP entry message (so that configuration version can
be included).

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 to open a new transcript on every queue run; when returning
an SMTP transcript, only send the last half (i.e., that part which
describes the sending half).

process timeouts like normal errors, so that they will get delivered to
the correct address (i.e., the Errors-To: address)

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

The routine "sendto" is now a system call (yeuch!); change our sendto
to "sendtolist"

avoid putting in a full name in network forward operations
