I'm looking for assistance from anyone out there that has run into 
this problem before or that can assist me.
 
I'm trying to compile a BBS program designed to run under Unix System 
V or SCO Xenix called XBBS.  I'm running Unix System V 3.5 on an AT&T 
3B1 and also have the Utilities/Developement Set V3.5.  I've compiled 
the code (.c files) to object code.  The problem appears to happen 
during the link phase.  It aborts and give me this error:
 
undefined symbol                first referenced in file
 
opendir                                bbscconf.o
readdir                                bbscconf.o
closedir                               bbscconf.o
 
ld fatal: Symbol referencing errors.  No output written to bbsc1
*** Error code 13
 
The problem as I understand it is correctable.  The symbols are apparently 
a Berkley enhancement.  It is also my understanding that there is a 
PD program for Unix System V to emulate/solve this problem.  Can anyone 
help?
 
Thanks

I have been experiencing a little problem with various individuals
sending me a substansial amount of unwanted email. Does anyone have
a good hack to refuse email from particular users?

The system is a Sequent S-81 running Dynix. I use the default BSD mail 
system.

Please email me direct with the responses.

Thanks.

Some time ago I implemented a rather neat hack (if I may say so) that
solved such problems in an interesting way.  I converted incoming mail
from several mailers into news, so that, for instance, my mail was sent
to the to.jc newsgroup, which was at the head of my .newsrc file.  The
news directory was owned by the user, read/write by the user and the
news group, and write-only to the rest of the world.

The rn users especially liked this hack; it meant that their kill file
could be used to ignore mail from known junk-mail sources, occasionally 
including much of the local bureaucracy.

Of course, I didn't carry the code away with me.  I've occasionally
wished I had, given the klutzy mailers on most systems.  On the other
hand, it wouldn't be hard to do it again.  Go ahead...

(Let's see, there's gotta be some problem with this approach; else why
are mailers and news kept apart everywhere?  I assume someone will tell
me why this is an idiotic idea.  ;-)

Sure.  Use my Deliver program (currently at 2.0 patch 5; patch 6 out
soon).  Delivery files are shell scripts which control delivery of
each message.  A good one for filtering unwanted users is:

	:

	u="$1"
	from="`header -f from $HEADER`"

	# Kill mail from junk mail sources.
	case "$from" in
	*bozo@bozosite* ) echo DROP; exit ;;
	*kludge@hacksite* ) echo DROP; exit ;;
	esac

	# Oh goody, we keep it.
	echo "$u"

Deliver 2.0, at finer archive sites everywhere.

Not Just Another Deliver Hacker,
