How do I allow posting from non-subscribers on a Mailman list?

Prerequisites / Minimum Requirements

• Ownership of an active Mailman list
• Using the CU Wireless network or VPN from home

How to Steps

You may have a list that you wish any member of Creighton to post to even if they are not subscribed. To allow this:

1. Go to [Privacy Options], then [Sender Filters] and scroll down to List of non-member addresses whose postings should be automatically accepted.

• If you wish to only allow other Creighton University addresses to post, put the following in the text box:
  • ^.+@creighton\.edu$
  • ^.+@.+\.creighton\.edu$

• If you want to allow the world to post, put in the following:
  • ^.+$

2. Then scroll down and Submit.
3. If you have no other entries on that page, you can also just scroll down to Action to take for postings from non-members for which no explicit action is defined and click Accept, then Submit.

Note:  Be very careful with these last two options as your list may be inundated with unwanted emails that will not go to the list owner for approval and will simply be re-routed to the subscribers. This can include messages laden with spam or viruses that your readers may find dangerous or inappropriate.
