I've read the tutorial to create mailinglists:

http://www.iredmail.org/docs/ldap.add.mail.list.html

Is there another way to fill groups (maybe adding an attribute to the group as memberUid)? I would like to administrate the group out of the group entry.

My second question is if it possible to make the mailing list visible in the addressbook just for a certain group? (maybe POSIX-group in LDAP?)

Thanks in advance!
