I registered our moodle 2.0 site some months ago within moodle. I verified within the registration process that e-mail alerts will be sent to me.

Registration process worked without any problem. But now, some months later, I didn't receive any e-mail alerts, although there have been some alerts on http://moodle.org/security/ since.

When I log into http://lists.moodle.org/info/securityalerts with our mail adress given within registration process, I get
AUTHORIZATION REJECT (info) List information is restricted to list subscribers.

Re-Registering this week didn't change anything. Any help would be appreciated.
