Guidelines
List configuration settings can be established at two points:
- When requesting the list: LISTSERV list request form allows you to use drop-down lists to select from the available options for each configuration setting
- After the list is created: Change the list settings after your distribution list is created by editing its header manually or by using the configuration tabs in the web interface. For details on how to access the List Configuration menu tabs, see the related item Changing LISTSERV list security settings.
Attachments
LISTSERV can handle attachments in several different ways. These settings are found on the Attachments tab on the List Configuration screen. For more information, review LISTSERV's Access Control Keywords.
| Settings Action |
Description |
List Header Keyword and Value |
| Allow all attachments |
All attachments sent to list are distributed to all subscribers
This simple method can also open a list to virus-related attachments |
Attachments= Yes |
| Remove attachments from messages |
All attachments are stripped from incoming messages before messages are distributed to list
This protects list from email-borne viruses, but prevents subscribers from posting legitimate attachments for distribution |
Attachments= No,Filter |
| Reject messages with attachments |
Any messages with attachments are rejected and sent back to sender without being distributed to list
Often, previous option will be more effective |
Attachments= No |

Archives
LISTSERV can keep archives of all messages sent. IT Services policy requests the creation of these archives as a way to identify lists that fall into disuse and can be deleted. These archives can be very useful to list subscribers who have accidentally deleted a message or want to refer to older list messages. Archives are available at http://listserv.miamioh.edu/archives/listname.html where listname is the name of the list. These archives will exist and be available even if List Visibility is set to hidden (Confidential= Yes), there simply will not be a link to the archives on the list index page. For more information, review LISTSERV's List Maintenance and Moderation Keywords.

For more information, review LISTSERV's Distribution Keywords.
