Anyone ever use rsync to propagate the sudoer file?

I have the following in the rsyncd.conf file:

[sudo]
comment = AIX sudoer filer
path = /home/das/aix/sudo
outgoing chmod=Du+rwx,go-w,Fg-wx,o-rwx
incoming chmod=Du+rwx,go-w,Fg-wx,o-rwx

I run the following on the client side:

rsync -avvz 192.168.84.83::sudo /etc

What I need is the file to have the permissions of 440 what I get is
640 on the file and 770 on the directory /etc which really makes a
mess of things.

Thanks
