expunge debugging/nonstandard/trojan horse commands from smtp,
logging attempts to use them; log name/address of host from which mail received
("mail from" may not include it or may lie); don't allow debug to affect
permissions locally; change some of the non-system syserrs to syslog at lower
priority; still need to unifdef remaining debug code

add iferror to loop termination conditions to avoid loops from

Assorted changes from Guy Harris <rlgvax!guy>: mostly lint & USG

fix from Bill Nowicki -- don't return an error if the connection times
out, since we haven't accepted responsibility yet.

Fixes two nasty problems, both pointed out by Bill Nowicki at Stanford:
I/O errors on input in collect would cause infinite loops, and a protocol
error (or other error that would call smtpquit abnorm

Check for I/O error on close of temp file -- i.e., last buffer flush

log queueid <=> message-id correspondence

Give an error if the message is terminated with an EOF and we are
running SMTP (it must be terminated with a dot).

split operation mode ("-bx" flag) and delivery mode ("d" option)
so that operation mode can apply to SMTP/daemon connections also.

Put temporary file mode on the F option

change inheritance for macros in envelopes; be able to canonicalize
non-domained names by appending domain from sender; call ruleset 3
explicitly before doing other rulesets; some general cleanup.

allow continuation lines in .cf file (particularly in headers)

change $i to $j; $i is now queue id; put "Received:" format in .cf
file; minor cleanup

assign a unique id to each transaction that can be determined from
the queue file name.
