Cannot overwrite files in ws-ftpd

I'm sure the answer to this is really easy but for some reason it escapes me.

I can't overwrite files through ftp on my server. It doesn't matter whether I log on as a "real" user or a guest user (in a chroot) environment. The problem has to be in the ftpaccess file but after several passes through the man pages and numerous tests it still doesn't work.

The relevant section of the ftpaccess section is

realuser me (me is the name of my actual login account)
guestuser *

class staff real *
class remote guest *

#defumask 027 remote

message /guest.hello LOGIN remote
message /real.hello LOGIN staff

chmod yes real,guest
delete yes real,guest
rename yes real,guest
overwrite yes real,guest

I know that I am getting set up correctly because depending on the account I am using I either get the guest.hello message or the real.hello message.

What am I doing wrong?

Apparantly you need to duplicate the lines

chmod yes real,guest
delete yes real,guest
rename yes real,guest
overwrite yes real,guest

in the ftpaccess file. The default file that comes with the installation has two sets defined. When I created two sets in mine it started working.

Back to the coal mines......

I downloaded the latest version of wu-ftpd at the same time. The problem I was getting appears to have been solved in this version.
