upas/mlowner addressfile listname

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.
