For the past couple of days, my Landesk Service Desk 7.2.6 system is giving the error 'Exception of type 'System.OutOfMemoryException' ws thrown' with the source being Outbound Mail Engine. The system has on average used about half of its available memory, and emails are still processing. The mail transport server was having an issue, so we are pointing it to a new mail transport server, but we are still receiving the error. I only altered the one areas line under Mail administration to point the outbound mail to the new server. Is it possible the system is still attempting to use the faulty mail transport server, or does the error point to something else.
