preliminary hacks for multiple SMTP transactions per connection: make
assignment of multiple queue id's more efficient, make prefixes two
characters (e.g., qfAA99999), pass the file name to freeze and thaw,
add a mailer flag saying we are talking to one of our own kind.

Handle Reverse-Path in some reasonable way. You must put the 'X'
flag (M_FULLSMTP) in the local mailer's flags to get this line.

never use ruleset 3 alone -- perhaps the standard use of ruleset
three should go now, since noone uses it alone.

put 050 in from of recursive smtp messages

user SMTP fixes to talk to ISI

clean up canonname

clean up reply code processing some more; in particular, give more
detail in many messages. process connection failures correctly.

fix serious botch in SMTP reply code delta; change a bunch of
"Internal error" codes to a new "Remote protocol error" -- so that
I don't get blamed for things that other systems do.

do a better job at interpreting SMTP reply codes

make "sleep" work correctly even in the face of other events; clean
up the queue processing: child queue runs now go away when done. more
debugging logging is needed to verify that this works right

more general event mechanism

change debug level to a debug vector; add levels on logging (and the
-L flag); change logging to be by message-id; elevate message-id;
some lint-type cleanup

improve debugging: flush transcript before doing things that might
take a long time; add some info to debugging output

put timeouts on net reads

do some stuff to add a "HOPS" command -- it seems like it would
be easier and smarter to count Mail-From: lines.

improve SMTP error reporting

pass lint. notice that definitions in llib-lc have changed for
alarm() and sleep() calls {arg was unsigned, is now int}.

finish implementing envelopes. it's not completely clear to me that
this is really the way to go, but it seems clearly better than what
i had before. this delta includes many other minor changes, so it
should probably not be blithely removed.

try to install envelopes. is this really worth it???

clean up error handling in IPC case; fix a minor bug in headers in
queueing code; make SMTP mail multi user per connect.

configuration. This tries to make the configuration file (cf.m4) be

cleanup from cbosgd (Mark Horton) testing; some internals, mostly
configuration. This tries to make the configuration file (cf.m4) be
much more general, but I fear it is doomed to failure -- it may be
better to just tell people to roll their own.

cleanup so it will go through lint without any fancy grep -v's;
change the way SCCS Id's are handled.

integrate user SMTP into sendmail itself. If there is no $u arg
in the mailer argument list, SMTP is run. This can be used directly
over the Ethernet or to any clever mailer. We still need to edit
spooled control files to remove recipients that have been successfully
sent during queue processing.
