Unlike Listproc listowners, Mailman listowners do not have automatic posting rights to the list.

Lists can be moderated by both owners and moderators.  The difference between an owner and a moderator is that an owner has access to all the administrative functions of a list, whereas a moderator only has the ability to approve or reject messages.  To add owners or moderators, go to the General Options section, and look for the owner and moderator fields.  Enter the information as necessary.

The address that will be posting to the one-way list can either be set to unmoderated (if a subscriber) or added under Privacy Option, Sender Filters
- List of non-member addresses whose postings should be automatically accepted.

If your list is a low-volume, one-way or moderated list that has had a problem with viruses or spam getting through to the list due to the moderator's address appearing as a forged sender address, there is a way to configure the list so that all posts, including those from a moderator's address, are held for approval via the Web.

Under Privacy Options, Recipient Filters
Ceiling on acceptable number of recipients for a posting. (max_num_recipients)
If a posting has this number, or more, of recipients, it is held for admin approval. Use 0 for no ceiling.
To hold all posts, including the moderator's, for Web-based approval, set this to  1
