You can configure the Router to respond in several ways when a mail file exceeds its quota, each representing a higher level of enforcement. The least restrictive response is to have the Router issue automatic notifications to users when their mail files exceed the quota. If users fail to respond to notifications, you can hold pending messages in MAIL.BOX or return messages to the senders as undeliverable until the users reduce the size of their mail files.
In addition to setting a quota, you can configure a warning threshold and use it as the basis for providing users with advance notice that their mail files have grown too large. For example, you might set a warning threshold of 25MB on a mail file that has a 30MB quota. In the Configuration Settings document, you can enable the Router to send notifications to users who exceed their warning threshold. If you enable this option, the Router delivers an Over Threshold Warning to users whose mail files exceed the warning threshold. Sending such warnings allows users to reduce the size of their mail files before they exceed the quota.
Along with the methods the Router uses to enforce quotas, the Notes client also displays a warning to any user who has exceeded their designated warning threshold or quota whenever the user attempts to send mail.
