Message Store notifications that a user himself is overquota

Notifications to a user that that user himself or herself is overquota are generated by the Message Store (if the   Message Store option is enabled), or generated due to the system administrator  using the   utility to manually generate such  notifications; they are not generated by the MTA, and, since such  warnings are deposited directly into the store bypassing the MTA, they  do not even go through the MTA. (Thus note that the warnings to a local user of that selfsame user being overquota, or near to overquota, are a  separate and very different case than an MTA-generated  notification telling a message sender that his/her message could not be  delivered to its intended recipient with the reason for nondelivery  happening to be that that intended local recipient was overquota.)

Such warnings to a user that he/she himself/herself has gone overquota, or is near going overquota, are configurable via a number of Message Store   options  (  options in Unified Configuration,  corresponding to legacy configuration   and    configutil parameters), as well as    features. The handling of quota is a complex subject in itself; please see the Administration Guide for much more  complete discussion, as the discussion here is simplified and merely  attempts to give an (over-simplified) orientation.

The  Message Store option controls whether the Message Store generates  quota-related notifications to the user. The reporting of user overquota status normally is triggered by a user&#x27;s mailbox reaching the threshold specified by the    option (legacy configuration   configutil parameter). However, if   is set,  (legacy configuration   ), then notifications  are not generated until the user&#x27;s mailbox actually exceeds their specified  quota. Besides depositing a warning message into a user&#x27;s mailbox when that user first goes over the quota notification threshold, for users of  IMAP clients that support the IMAP ALERT functionality, the warning  message will be displayed on the user&#x27;s client each time the user  selects a mailbox. Also, the   Message Store option (in legacy configuration, the configutil parameter   ) controls the periodic  sending of additional overquota warnings if a user remains overquota.

A Messaging Server administrator may also manually trigger generation of a different form of quota warning message via the   utility.
