upas/mlowner addressfile listname

Mlmgr creates and updates unmoderated mailing lists. The -c option creates mail directories for both listname and listname -owner\f1, each containing a pipeto file. Messages mailed to listname are sent to all members of the mailing list. Any Reply-to: and Precedence: fields are removed from the messages and new ones are added directing replies to listname and specifying bulk precedence. The envelope address for error replies is set to /dev/null .

The mailing list membership is the file /mail/box/listname/address-list . This file is an add/remove log. Each line represents a single address. Lines beginning with a hash ( # ) are comments. Lines beginning with an exclamation point ( ! ) are removals. All other lines are additions.

Addition and removal entries can be appended using the -a and -r options to mlmgr . However, they are normally appended as a consequence of user requests.

To be added or removed from the list, a user may send a message to listname -owner containing a key word in the header or body. The key words are:

subscribe - add my From: address to the list remove - remove my From: address from the list unsubscribe - remove my From: address from the list

Addition and removal events cause notification messages to be sent to the added/removed address. In the case of addition, the message describes how to be removed.

Ml and mlowner are the programs that receive messages for listname and listname -owner respectively. Appropriate calls to them are inserted in the pipeto files created by mlmgr .

Ml 's -r option sets the Reply-to: field in the mail sent out by ml.
