Why can't I get secure mailing lists to work in IMS 5.1

I am having problems getting secure mailing lists to work at all. I

have been battling with iPlanet support and have gotten no where. Evan

though a local user or a remote email user is listed as allowed senders

in the IDA, it still will not let either send a message to the list. I

checked to make sure that the allowed senders showed up in the LDAP

entry as mgrpallowedbroadcasters and they are. I evan set up a test

server from scratch and ran into the same issue. Each time an allowed

user tries to send they get the following error:

SMTP Error: 5.7.1 you are not allowed to use this list:

allstudents@host.edu

Anyone else seeing these issues? Does anyone what could be going

wrong?
