Sending mail via uucp

[David I. Berg]

We are trying to send mail from a SUN 3/60 running 4.0 using the standard
uucp mailing address format, i.e. cod!dberg.  The process fails on the SUN
and sendmail (on the SUN) returns the following mail message:

Thinking that it might be a write permission problem (from the '554' in
the message), we changed the permissions on the C. and D. directories in
/usr/spool/uucp with no better result.  I then ran uux directly with the
following result:

** START **
arg - cod!rmail:arg -  cod!rmail
file - D.omdacX006c
ASSERT ERROR (uux)  pid: 14821  (3/1-12:35) CAN'T OPEN D.omdacX006c (0)

This seems to prove my theory, but with the permissions set to 777 on
/usr/spool/uucp/D. it should be able to write it. I even created a file in
that directory with the next file name it would attempt to write, set the
permissions on it to 666, and got the same result.  Could it be that uux
is trying to write to another directory?

Any ideas?  Thanks in advance for any assistance.  (Please Email your
responses.)

P.S. We have no problem performing the same process on a platform running
System V/3.2.
