Definition

Maximum number of messages permitted for a user is set with mailMsgQuota. This is a cumulative count for all folders in the store.

This attribute also can specify the number of messages allowed for a particular folder or message type.

Although mailMsgQuota is a single-valued attribute, you can use it to specify multiple quota values. You can set individual quota values for specific folders and message types. For details, see Specifying Quotas for Folders and Message Types.

If the mailMsgQuota attribute is missing, the system default quota is used. This is defined by the configutil parameter store.defaultmessagequota.

During server configuration, quota enforcement must be turned on for mailMsgQuota to take effect. Both soft and hard quotas can be set. (See the Sun Java System Messaging Server 6.3 Administration Guide.)

The MTA option override is LDAP_MESSAGE_QUOTA.

To specify a mailMsgQuota value for the user's entire mailbox tree, use the following format:

mailMsgQuota: msgquota

where

msgquota is the number of messages.

msgquota Values

Valid values for msgquota are up to a maximum of 4294966272. Specifying a msgquota value of 0 will mean that no mail will be delivered. You can also use the values shown in the following table:

Specifying Quotas for Folders and Message Types

To enable the quotas for individual folders or specific message types, you must run the configutil command with the parameters store.quotafolder.enable and store.typequota.enable.

To enable and configure message types, you also must enable the configutil parameter store.messagetype.enable and configure other configutil parameters.

Guidelines for Specifying Multiple Quota Values

You can specify the following mailMsgQuota values for a user's mailbox tree:

• Quota values for specific folders in the user's mailbox

• Quota values for specific message types such as voice mail or text messages. A message type quota applies to messages of that type in all folders in the user's mailbox.

• A default quota value that applies to all folders and message types in the user's mailbox that are not explicitly assigned quotas.

The following guidelines apply when you assign multiple quota values for a user:

• Quotas do not overlap. For example, when there is a quota for a particular message type or folder, messages of that type or messages in that folder are not counted toward the default quota. Each message counts toward one and only one quota.

• The total quota for the whole user mailbox equals the sum of the values of all the quotas specified by default, type, and folder.

• Message type quotas take precedence over folder quotas. For example, suppose one quota is specified for a user's memos folder and another quota is specified for voice messages. Now suppose the user stores eight voice messages in the memos folder. The eight messages are counted toward the voice-mail quota and excluded from the memos folder quota.

Formatting Quota Values for Folders and Message Types

To specify mailMsgQuota values for folders or message types, use the following format:

mailMsgQuota: {msgquota}[;{name}%{msgquota}]...

where

{msgquota} is the number of messages. For a description of the valid numeric values, see msgquota Values.

{name} is the name of the folder or message type.

The semicolon (“;” ) is a separator that separates multiple quota values.

The percent sign (“%”) associates a folder or message-type name with the quota value that follows it.

Additional Formatting Guidelines for Quota Values

• The first {msgquota} in the syntax shown above–that is, the first quota value entered after the mailMsgQuota attribute—does not have a name. This value represents the default quota for all folders in the user's mailbox that are not explicitly assigned quotas. The default value applies to all the unnamed folders combined, not individual folders.

• A message-type name starts with a pound sign (“#”).

• A folder name does not start with a pound sign (“#”).

• The “%” and “#” signs are not allowed in folder names or message-type names.

Example

To specify a quota of 2,000 messages:

mailMsgQuota: 2000

To specify the system default quota, do not add mailMsgQuota to the LDAP entry. Or you can use the following value:

mailMsgQuota: -2

To specify a default quota of 2,000 messages for all user folders not explicitly assigned a quota; a voice-message quota of 100 messages; and a quota for the Archive folder of 4,000 messages:

mailMsgQuota: 2000;#voice%100;Archive%4000

In the preceding example, the 2,000–message default quota includes messages in all user folders except the Archive folder; it also excludes voice messages. The 100–message voice-mail quota includes voice messages in all user folders, including the Archive folder. The 4,000–message Archive-folder quota includes messages in the Archive folder and its subfolders; it includes messages of all types except voice messages.
