Check the queue and see why they are in that queue, check the status of the messages. If the exch services are stopping then this could be ehy you cant connect via telnet. This could also be the reason for the queues. Check the event logs for any further info and post errors. If you have any other product doing scanning email for AV/AS, try to stop and test. Sukh
