| Message field | Description |
| Notification type | Describes why the user received the notification. For example, an over quota report explains that an incoming message caused the user's mail file to exceed the quota set for their mail file. Over quota and quota warning reports contain default text, which you can customize. |
| Message headers | The sender (FROM field), recipients (TO and CC), subject of the effected message. |
| Message size | The size of the affected message, in KB. |
| Current mail file usage | Database usage or current size of the user's mail file, in KB. |
| Current quota settings | The warning threshold and quota currently set for the user's mail file. |
| What you should do | Explains what action, if any, was taken -- for example, whether the message was returned to the sender or is being held for retry; and provides instructions explaining what actions the user should take to reduce the size of the mail file -- for example, deleting or archiving messages. If you customize the text of the notification to provide users with additional instructions or information, the text you add appears as part of the Notification type information at the beginning of the message. |
