0 - No space allowed for user’s mailbox. 

–1 - No limit on space usage allowed.  

-2 - Use system default quota. (configutilparameter store.defaultmailboxquota)

mailMsgQuota

Maximum number of messages permitted for a user. This is a cumulative count for all folders in the store. Special values:  

0 - No message allowed for user’s mailbox. 

-1 - No limit on number of messages allowed.  

-2 - Use system default quota. (configutil parameter store.defaultmessage.quota.)

mailUserStatus

active - mail is processed as normal. Default is active.

inactive - user’s mail account is inactive. A transient failure is returned.

deleted - Account marked deleted and ready for purge. Permanent failure returned. Access to mailbox blocked.

hold - Mail sent to the hold queue and access to the mailbox is disallowed

overquota - The MTA will not deliver mail to a mailbox with this status. This is the status set when the configutil parameter, store.overquotastatus is on.

mailDomainDiskQuota

Bytes of disk space allowed for the cumulative count of all the mailboxes in a domain. A value of -1 means no limit on space usage. (Default) To enforce the domain disk quota run the command: imquotacheck -f -d domain

mailDomainMsgQuota

Maximum number of messages permitted for a domain, that is, the total count for all mailboxes in the store. A value of -1 means no limit. (Default). To enforce the domain message quota run the command: imquotacheck -f -d domain

mailDomainStatus

Status of the mail domain. Values and default are the same as mailUserStatus.

store.quotaenforcement

Enable quota enforcement When off, the quota database is still updated, but messages are always delivered. Default: On 

store.quotanotification

Enable quota notification. Default: On 

store.defaultmailboxquota

Store default quota by number of bytes. Default: -1 (unlimited) 

store.defaultmessagequota

Store default quota by number of messages. Numeric. Default: -1 (unlimited) 

store.quotaexceededmsg

Quota warning message. If none, notification is not sent. Default: None. 

store.quotaexceededmsginterval

Interval, in days, for sending overquota notification. Default: 7 

store.quotagraceperiod

Time, in hours, a mailbox has been overquota before messages to the mailbox will bounce back to the sender. Number of hours. Default: 120 

store.quotawarn

Quota warning threshold. Percentage of quota exceeded before clients are sent an over quota warning. Default: 90 

local.store.quotaoverdraft

Used to provide compatibility with systems that migrated from the Netscape Messaging Server. When ON, allow delivery of one message that puts disk usage over quota. After the user is over quota, messages are deferred or bounced, the quota warning message is sent, and the quota grace period timer starts. (The default is that the quota warning messages are sent when the message store reaches the threshold.) Default: Off, but is treated as on if store.overquotastatus is set, otherwise the user can never go over quota and the overquotastatus is never used.

local.store.overquotastatus

Enable quota enforcement before messages are enqueued in the MTA. This prevents the MTA queues from filling up. When set, and a user is not yet over quota, but an incoming message pushes the user over quota, then the message is delivered, but the mailuserstatus LDAP attribute is set to overquota so no more messages will be accepted by the MTA. Default: off
