Deliver restrictions for lists ignored

Hi

I'm running iRedmail 0.8.2 and iRedadmin Pro 1.8.1 (LDAP) on Ubuntu 10.04.4 LTS.

I'm having trouble with deliver restrictions on mail lists being ignored. Even if I set it to "members only" everyone can send mail to the lists. I know that it worked a while ago so I guess something have happend in when upgrading, not sure when though. Any suggestions?

Thanks // Tomas
