Here is what Argo says about MM3 lists being deactivated. It sounds like it is more of an unofficial state if a list is “inactive”. It sounds like we would need to make this a process and put the notes in Confluence or something. Recommended way Configure the list so it cannot be used: * Disable or restrict posting * set posting to moderators only, or * hold/reject/discard all posts * Disable new subscriptions * close subscriptions or require admin approval * Hide the list * remove it from the public list index if desired * Optionally update the description * e.g. “This list is inactive and no longer accepts posts.” If you want it fully dormant A common setup is: * no new subscriptions * no posting from members or non-members * archives remain available * list hidden from public discovery That preserves the list and its archives without deleting it. Things not to use * Ban list: only blocks specific addresses, not the whole list * Deleting the list: removes it rather than disabling it In Postorius Look in your list’s admin pages under areas like: * Settings * Subscription policy * Message Acceptance * Privacy * Archiving Exact labels vary by Mailman/Postorius version. Step-by-step Postorius path for making a list read-only/inactive. Make a Mailman 3 list effectively inactive in Postorius There isn't usually a single Disable list button, so do these settings instead. 1) Stop new subscriptions Go to: * List → Settings → Subscription Policy Set options so: * new subscriptions are closed or require admin approval * if available, disable self-subscription entirely 2) Stop posting Go to: * List → Settings → Message Acceptance or sometimes: * List → Settings → Privacy Set posting so that: * only moderators can post, or * all posts are held, rejected, or discarded If you want the list completely inactive, use: * reject all non-member posts * restrict member posts as well, if your version allows it 3) Hide the list from public view Go to: * List → Settings → Identity or * List → Settings → Privacy Look for options like: * Advertise this list * List is public * Display on list index Turn that off. 4) Keep archives if desired Go to: * List → Settings → Archiving Choose whether to: * keep archives visible * make archives private * disable new archive visibility if needed 5) Add an “inactive” note Go to: * List → Settings → Identity Update: * Description * Info * Welcome / goodbye / rejection text if available Example text: This mailing list is inactive and no longer accepts new posts or subscriptions. Practical "inactive list" recipe A good combination is: * subscriptions: closed * posting: moderator-only or reject all * public listing: off * archives: kept * description updated to say inactive ________________________________ If you want the strongest lock-down If your Postorius version exposes these controls, also check: * DMARC / moderation / member posting controls * Acceptable aliases * Non-member rules * Member moderation You can set: * non-members: reject * members: moderated * default action: hold or reject ________________________________ If you don't see these exact menu names Postorius labels vary by version. Look for sections with names like: * Subscription Policy * Message Acceptance * Privacy * Archiving * Identity Barb Doukas – CELS IT Technical Support Engineer Level 1 ARGONNE NATIONAL LABORATORY<https://www.anl.gov/> 9700 South Cass Avenue; Building 240, Office 2.A.13 Lemont, IL 60439 P: 630-252-6525 [email protected]<mailto:[email protected]> [Image] Impact | Safety | Respect | Integrity | Teamwork -
