When the number of unread messages in a gateway's mailbox folders (MTS-IN, MTS-OUT, etc) reaches the limit set by PR_EMS_AB_MDB_UNREAD_LIMIT, the information store stops the transfer of messages from the MTA to the gateway for the length of time specified by the PR_EMS_AB_MDB_BACKOFF_INTERVAL property.
