SNMP Trap: Mailbox Status
-------------------------

A trap is generated when the local mailbox reaches 200 plus emails.

Identification

* The originating IP / hostname is used to identify the system generating the traps
* The NMS is responsible for associating traps with each managed system, along with clearing 
  of alarms and escalation to the relevant system operator
* The trap OID is generic  for various SNMP events monitored by the system
* The SNMP system name is included as part of the variable binding to assist identification: 

::

  .iso.org.dod.internet.mgmt.mib-2.system.sysName.0 = standalone

Trap OID

* .iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotifications.mteTriggerFired

Variable Bindings - Mailbox email messages reach 200 

* .iso.org.dod.internet.mgmt.mib-2.system.sysUpTime.0 = 2 minutes (12065)
* snmpTrapOID = mteTriggerFired
* .iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotificationObjects.mteHotTrigger.0 = 'WARNING: The total messages in the local mailbox for %s has reached in excess of 200'
* .iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotificationObjects.mteHotValue.0 = 1
* .iso.org.dod.internet.mgmt.mib-2.system.sysName.0 = standalone

Variable Bindings - Mailbox email messages reach 500 

* .iso.org.dod.internet.mgmt.mib-2.system.sysUpTime.0 = 2 minutes (12065)
* snmpTrapOID = mteTriggerFired
* .iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotificationObjects.mteHotTrigger.0 = 'INFO: Messages for <server info> auto archived as it reached more than 500'
* .iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotificationObjects.mteHotValue.0 = 1
