Mailing Lists at UD: Mailman mailing list instructions


IT no longer supports the creation of new Mailman lists. A Google Group will meet your needs instead.

How to use

From off-campus, you will need to connect using VPN for list configuration and administration. You may need to configure your list if the pre-configured options do not apply to how you want to use your list.

You can configure your mailing list at the your list's Web page. The URL will be of the form
substituting the name of your Mailman list for yourlist-name.

The Web page for users of your mailing list will have a URL like this one:
substituting the name of your Mailman list for yourlist-name.

When you log in with your "List Administrative Password," you will first see a page with the following information:

From off-campus, self-subscribers with UDelNet IDs will need to connect using VPN. Self-subscribers who do not have UDelNet IDs will need to send email to the list owner.

How to change a List owner

To change a list owner, the current list owner (or someone with access to the "List Administrator Password") may log in into the list administration Web page:
substituting the name of your Mailman list for yourlist-name.

If access is no longer available to the list adminstration web page, please submit a request and provide the current list information and the requested changes. For list owner changes, include the new owner's name and UDelNetID.

How to request that the "List Administrator Password" be reset

If you are a list owner, please submit a request, provide the name of the mailman list  and specify that the password is to be reset.

How to change a List name

If you are a list owner and need to change, please submit a request, provide the name of the old mailman list  and specify the name of the new mailman list. All information will be migrated from the old mailman list to the new mailman list, and the old mailman list will be removed.

How to request that a Mailman list be Deleted

If you are the list owner, please submit a request and provide the name of the mailman list to be deleted. Please include the title of the list and indicate that the archive of messages can also be deleted.
