rsync: a bit of confusion

[Payal Rathod]

Hi,
This is the first time I have setup rsync.conf like,

max connections = 20
syslog facility = local3
read only = true
hosts allow = 192.168.10.10
[qmail-control]
        comment = qmail-control
        path = /var/qmail/control
        read only = yes
        list = yes
        uid = root
        gid = root

Then from 192.168.10.10, I tried,
rsync -avz -e ssh root at 192.168.10.1:/var/qmail/control/* .
and it worked. So far so good. But then again it worked from 192.168.10.11
too and that too for other directories too. Even deleting the rsync.conf
file had no effect. What is wrong here? Is this not the way to
use rsync client? 

With warm regards,
