List Control

These options control how the list mailbox will handle messages.

General Tab

List owner

Address of person responsible for list maintenance.

Limit postings size

Causes messages over this size to be rejected

Subject identifier

Text to be added to the start of the subject line for each messages distributed out by this list. For example using a Subject identifier of [mylist] would cause all message from the list to have [mylist] prepended to the subject line.



Enabling this will allow new members to join the list by emailing to the list with “subscribe” (no quotes) in the subject line.

Records in the log who has subscribed/un-subscribed

Not used in ODBC list sources


Sends a message to the user who is subscribing for them to confirm they wish to be on the list. This helps prevent other people subscribing addresses “for a laugh”. If the user does not reply to the confirmation request, the user is not subscribed

Send notification to owner for subscribes and unsubscribes

The mailbox sends a notification to the list owner after a successful subscribe or un-subscribe.

Maintain archive of postings

Keeps the messages in the mailbox folder for that mailbox


The list owner can post to the list when this option is enabled. This forces all messages to the list to be sent to the list owner who can then decide which messages are suitable for publishing. This is useful when the list is a “Customer list” and you only wish the sales manager to be able to send messages to the customers via the list.

Only allow list members to post

Users must subscribe before posting to the list, if not the messages will be rejected.

Include Sender in postings

Sends a copy of the message to the sender.

Function as a distribution list

When this option in not checked, one message is generated addressed to all the list members (via BCC), and the To address in the header is shown as the list mailbox name. With the option checked a unique message is created for every list member and the To address is set to the address of the list member

Auto-manage members

Removes any address from which messages have bounced, after sending a second message and a confirmation request “do you still wish to be on this list?” This keeps the list current, with only valid email addresses on the list. This will have no effect on an SQL based list.
