Quotaoverdraft Option

The  Message Store option is used to provide compatibility with systems that migrated from the Netscape Messaging Server. When set to, the Message Store allows delivery of one additional message that puts disk usage over quota. After the user is over quota, any additional messages are deferred or bounced, the quota  warning message is sent, and the  quota grace period timer starts. The option is treated as being enabled if the  option is set.

Note that enabling  means that quota enforcement does not start until after a user goes over quota, and in particular, means that the   Message Store option (used to warn users that they are nearing their quota limit when strict, no-overdraft, quota limits are in effect) does not take effect.

The default value is: 0
