ezmlm only for broadcast

[Rene Casalme]

Any help is appreciated on this matter:

I want to use ezmlm on top of qmail to do the following:
1. create a mailing list
2. allow only broadcast, subscribers cannot post
3. only one user is allowed to subscribe and unscribe and post

Any guidelines or pointers are welcome.  I've read the ezmlm FAQ and I am
still at a lost.

Thanks


Rene
