JES COStemplates mail quotas greater than 4GB
Sun’s Java Enterprise System mail facilities have the capacity to provision users based on predefined classes of service (COS) which specify the types of services a user assigned to that COS can use, their mailbox size quota, number of message quota, and per message size quota. However, because the mailQuota attribute is stored as a 32-bit integer, the maximum value is 4,294,967,295 bytes (4GB). This recipe describes a way around this limit.
Faced with a client who wanted to set a limit on emails but needed a limit larger than 4GB, I started digging around. I found a reference to this that it will accept values for quotas in a unit format as well. Valid units are K for kilobyte, M for megabyte, and G for gigabyte. For example, to set a 10GB quota, use
mailQuota: 10G
