[alt.sources] mailx

joe@dayton.UUCP (Joseph P. Larson) (08/10/89)

I was given a copy of mailx by someone who said they got it from someone
who said it was public domain.  The only Copyright notice I found in the
entire distribution was on a support program called "xstr" -- "Copyright
1979 the Regents of the University of California, Berkeley".  No mention
at all if it can legally be redistributed.

Can someone tell me if it's okay to redistribute this?  I've made some
changes some people may like.  I figure I'm covered, legally, but if it
isn't supposed to be PD (ie: someone stripped the rest of the copyright
notices before I got it), I don't want to step on toes.

It's always* ok to post diff's to a source.  All you have to do is
assume that the receipient is patching the same level of source you
are sending him diffs for.  :)

Technically, of course, your 'diffs' are not allowed to contain the
source lines.  They should only contain offsets into the file to
remain perfectly legal.

It's not safe to assume that the absence of copyright notices means it's
okay to redistribute.  It may be covered by trade secret agreements, like
the AT&T Unix sources.  (In which case you should not have been given
access to it, but that's a separate issue.)  Some of the Berkeley stuff
is AT&T-derived and hence covered by Unix licensing; some is not.  It
can be a bit hard to tell.

Up until 4.3Tahoe, UCB did not go to the trouble of individually
copyrighting every single file in their source tree.  This was done
because it was impossible for UCB to separate their code from ATT code, so
they had to treat the entire BSD distribution as if it were protected by
ATT's licensing arrangements.  This is probably the version that you got.

In the 4.3Tahoe release, Keith Bostic (and, apparently, Kirk McKusick, but
I've only had contact with Keith) did a great deal of work in getting
large portions of UCB code certified as being free of ATT code, and
therefore not subject to ATT licensing restrictions.  John Gilmore
helped, and Rick Adams did the grunt work of creating a release tape that
has no non-free code (I believe; maybe Keith did that, too).  With that
the UCB Mail program, called mailx when ATT started to provide it with
their releases, had a UCB Copyright on it.  The UCB Copyright is
basically "a freely-redistribute, don't use our name to sell it, don't
blame us if it causes you any harm" copyright.

The upshot is, the version you have is probably illegal, either it's
covered by ATT license or someone stripped out the UCB Copyright.  You can
get a more current version on UUNET or by buying a tape from FSF, or by
asking someone with access to either of those, or a 4.3Tahoe source tape.

Apologies to anyone I might have slighted in my "who did what" summary,
above.

The only problem here, assuming the source is for /usr/ucb/Mail and not AT&T's
mailx, is the missing copyright notices.  Berkeley Mail has been certified
"AT&T-free" and is available in a number of places, notably UUNET.
