To Specify a Quota Threshold

A quota threshold is a percentage of a quota that is exceeded before clients are sent a warning. When a user’s disk usage exceeds the specified threshold, the server sends a warning message to the user.

When local.store.quotaoverdraft=on email notifications are not triggered until the user’s disk usage exceeds 100% of the quota regardless of the threshold set with store.quotawarn.

For IMAP users whose clients support the IMAP ALERT mechanism, the message is displayed on the user’s screen each time the user selects a mailbox and a message is also written to the IMAP log.

Steps

1. Click the Quota tab.

2. In the “Quota warning threshold” field, enter a number for the warning threshold.

   This number represents a percentage of the allowed quota. For example, if you specify 90%, the user is warned after using 90% of the allowed disk quota. The default is 90%. To turn off this feature, enter 100%.

3. Click Save.

   Command Line

   To specify a quota threshold at the command line:

   configutil -o store.quotawarn -v number

   where number indicates a percentage of the allowed quota.
