  Some time ago, I posted a question about a problem with rmail for
epoch 4.2 installation on a HP720 running HP-UX 9.01.    Thanks to
Gary Beckmann (gary@poseidon.dfci.harvard.edu) whose example leads to
a work around of the problem.   But neither of us can figure out a
real solution.   So I would like to report this and see if we can
understand the problem better.   

   The problem was whenever I use rmail, it gives me the following
error message   

movemail : Permission denied for lock file--see source file movemail.c

while root can use rmail without any problem.   Sounds like the
standard problem.   After following the comment in etc/movemail.c, I
allow movemail to be setuid and setgid,  

-rwsr-sr-x   1 root     mail       20480 Aug  4 17:03 movemail

It still doesn't work.   Meanwhile, rmail on our emacs 18.59 works.
Copying that binary to epoch/etc/movemal still gives the same error
message.   But following Gary's example, making /usr/mail writable by
the world  

  drwxrwxrwx   2 bin      mail        1024 Aug 24 14:51 /usr/mail

fixes the problem.   This is really just a work around.   We still don't
know how to fix it correctly.   So I call upon NetWidsom to help solve
the mystery.    Any thought?

For reference, the movemail I use on my system has the following perms.
(sgid, not setuid. Also it is owned by bin, not root which makes sense
since /usr/mail is owned by bin)

-rwxr-sr-x   1 bin      mail       

Also, you need to set your exec-directory to point to where movemail is.
Somewhere in your .emacs

 (setq exec-directory "/usr/local/emacs/etc/")

(or wherever movemail is on your system)

It wouldn't hurt to check that the path to movemail has read/exec
perm for bin...

You might want to check what movemail is being executed. It might not
be the one you think...

ESC-ESC exec-directory 

should show you what path is used.

Hope this helps

bruno.
