Commands understood by the mail list processor are as follows.

HELP	Produces summary of commands
JOIN [listname [address]]	Subscribe to mail list
LEAVE [listname [address]]	Unsubscribe from mail list
REVIEW	Show list membership
STOP	Stop processing commands (e.g. to avoid processing a signature)
SUBSCRIBE [listname [address]]	Subscribe to mail list
UNSUBSCRIBE [listname [address]]	Unsubscribe from mail list

You can join or leave a mail list by sending mail to the list-request address containing the above commands. 

Joining a mail list

To join the list called  members@toltbbs.com, send a message to members-request@toltbbs.com, containing:

JOIN in the message body.  Our Mail Server will respond with a mail message indicating the success or failure of your attempt.

If a list is moderated and Moderator Control Join is enabled, any JOIN message to this list will be forwarded to the moderator (unless of course the message is from the moderator herself). The moderator will determine whether the request should be honored, and if so can add the address manually (using the configuration console) or by email (by sending the appropriate JOIN command to the foobar-request address).

If you wish to subscribe under a different mail address, either include a Reply to: header in your mail message, or use the full form of the JOIN command:

JOIN foobar myname@mycomputer.mydomain

SUBSCRIBE is a synonym for JOIN.

Leaving a mail list

To leave a mail list foobar, send a mail message to foobar‑request@yourmachine.yourdomain, containing:

LEAVE

in the message body.

If a list is moderated and Moderator Control Leave is enabled, any LEAVE message to this list will be forwarded to the moderator (unless of course the message is from the moderator herself). The moderator will determine whether the unsubscribe request should be honored, and if so can remove the address manually (using the configuration console) or by email (by sending the appropriate LEAVE command to the foobar-request address).

If you have changed your mail address, and wish to unsubscribe from a list with your old address before subscribing with your new address, then include a Reply-to: oldname@old.domain header in your mail message.  oldname@old.domain will be removed from the mail list (but the response to your command will be sent to that old address).   Alternatively, use the full form of the LEAVE command:

LEAVE foobar oldname@old.domain

UNSUBSCRIBE is a synonym for LEAVE.

 

Subject Command Processor

To make it easier for users to join or exit mail lists, VOPmail will also accept some of the command processor commands when they are in the subject of  the email that is sent to the command processor (-request address). The commands are:

Join, Subscribe (no parameters accepted): Add the sender (based on the reply-to: or from: address) to the current mail list.

Leave, Remove, Unsubscribe (no parameters accepted): Remove the sender from the current mail list.
