mom: i don't care about send queues...

there's a rule called mailbox store: send queue > 25 in the exchange management pack. generally, this is an indication that mail is not going out for whatever reason. it looks specifically at this counter:

• object: msexchangeis mailbox
• counter: send queue size
• instance: _total

now why would you want to turn off a rule that's clearly pretty important? this counter looks at the number of messages in the store delivery. unfortunately, it includes deferred messages. since mom is simply looking at the counter value (and does not support dynamic thresholds), it has no way of interpreting the difference between deferred delivery (messages marked to deliver at a later time) and deferred submission (waiting retry from delivery failure).
