Setting Account Quotas
You can specify mailbox quotas and the number of contacts allowed for each account through the Zimbra administration console.
Account quota is the amount of space in megabytes that an account can use. The quota includes email messages, Calendar meeting information, task lists, files in Briefcase and RSS feed folders. When the quota is reached, all email messages are rejected and users cannot add files to their account. If you set the quota to 0, accounts do not have a quota. Alternately, you can configure the zimbraMailAllowReceiveButNotSendWhenOverQuota attribute to TRUE. When set to TRUE, a mailbox that exceeds its quota is still allowed to receive new mail and calendar invites. See Account Quota and the MTA on page 44.
You can view mailbox quotas from the administration console, Monitoring, Server Statistics.
Users can be notified that their mailboxes are nearing their quota. The percentage threshold for quota notification can be configured. When this threshold is reached, a quota warning message is sent to the user. The quota percentage can be set and the warning message text can be modified in the Advanced tab settings for COS and Accounts.
The Address Book size limit field sets the maximum number of contacts a user can have across all of their address books. When the number is reached, users cannot add new contacts.
