Lotus Domino Administrator 8.5 Help - Setting quota controls for the Router

MAIL

Setting quota controls for the Router
1. Make sure you already have a Configuration Settings document for the server(s) to be configured.

2. From the IBM® Lotus® Domino® Administrator, click the Configuration tab and expand the Messaging section.

3. Click Configurations.

4. Select the Configuration Settings document for the mail server or servers you want to administer, and click Edit Configuration.

5. Click the Router/SMTP - Restrictions and Controls - Delivery Controls tab.

6. In the Quota Controls section, complete these fields:

Field Enter

Over Warning Threshold Notifications Specifies how often the Router delivers notifications to users who exceed their warning threshold.
Choose one:

None - The Router does not deliver notifications when mail files grow larger than the specified warning threshold.
Per Message - The Router delivers a notification for every message it delivers after the mail file exceeds the specified warning threshold.
Per Interval N - Send notifications at a specified interval until the user deletes or archives enough messages to bring the size of the mail file below the specified Warning Threshold. When this option is selected, an additional field, "Warning Interval Minutes," appears.

Warning Interval Specifies, in minutes, how long the Router waits to send the next Over Warning Threshold Notification

Over Quota Notification Specifies how often the Router delivers notifications to users who exceed their quota.
Choose one:

None - The Router does not deliver notifications when mail files grow larger than the specified quota.
Per Message - The Router delivers a notification for every message it delivers after the mail file exceeds the specified quota.
Per time interval - When a message delivery is attempted and no notifications were sent during the previous time interval, the router sends an "over quota" notification to the user's mail file. Over quota notifications are triggered by normal mail delivery; therefore, over quota notifications may not be sent at the exact time interval setting. The router limits the number of notifications sent to one notification during each time interval.

Error Interval Specifies, in minutes, hours, or days, how long the Router waits to send the next over quota notification.

Over Quota Enforcement Specifies the action the Router takes when receiving new mail for a user whose mail file is larger than the specified quota.
Choose one:

Deliver anyway (don't obey quotas) - (Default) The Router continues to deliver mail to a mail file that is over quota.
Non Deliver to originator - The Router stops delivering new messages to the mail file and returns a nondelivery message to the sender reporting that the message could not be delivered because the intended recipient's mail file was full.
Hold mail and Retry - The Router stops delivering new messages to the mail file and temporarily holds incoming messages in MAIL.BOX until space is available in the mail file. After an interval, the Router tries to deliver the message. If the user has sufficiently reduced the size of the mail database by the next scheduled delivery attempt, the mail is delivered. Messages that cannot be delivered before the expiration time (default =1 day) are returned to the sender as undeliverable.

If you choose this option, the document displays additional fields where you can specify how the server handles held messages.
Note To prevent an excessive number of messages from accumulating in MAIL.BOX when this option is selected, it's best to have Domino calculate database size based on usage, rather than file size.

7. If you selected "Hold mail and Retry" in the "Over Quota Enforcement" field, complete the following:

Field Description

Attempt delivery of each message Pending messages may be of different sizes. A mail file that has reached its quota may have sufficient space available to fit some messages, but not others. Use this field to specify whether the Router delivers messages small enough to fit the available space in a destination mail file. Choose one:

Enabled - The Router attempts delivery of each new message. Messages that fit the available space are delivered. Other messages are held.
Disabled - After a mail file reaches its quota, the Router holds all messages until the file size is reduced.

Maximum number of messages to hold per user Specifies the maximum number of messages that the Router will hold in MAIL.BOX for a given mail file. After the number of pending messages reaches the specified number, the Router returns a delivery failure report to the sender of each additional message in first-in, first-out order.

Maximum message size to hold Specifies the maximum size, in KB, of messages that the Router can hold in MAIL.BOX for over quota users. If a message larger than the specified size is received for the user, the Router returns a delivery failure report to the sender.

8. Click Save & Close.

9. The change takes affect after the next Router configuration update. To put the new setting into effect immediately, reload the routing configuration.

Overriding quotas
Administrators can provide users who are over quota with temporary access to their new mail by:

Modifying the quota currently in effect for the user's database.
Changing the Router setting, so that the Router ignores database quotas and delivers mail. If you set the Router to ignore database quotas, all users who exceed their quotas are able to receive mail.

To permanently change a quota, reset its size value.
