Hi there,

I had the same issue. The phenomenon was that the permissions of the /var/run/courier/authdaemon/ folder was 750 after reboot. When I saved the mail configuration in ajenti it went properly (then it was 755). But after a new reboot everything was broken again....

So I searched for the init script of the courier-authdaemon and this led me to success.

This script overrides the permissions on every reboot.

In /etc/init.d/courier-authdaemon there is this line (around 39):

mkdir -m 0750 $rundir

change it by:

mkdir -m 0755 $rundir

save it, that's it!
