Configure the message transfer agent (MTA) frequency so that queues are cleared quickly. This prevents queued messages from accumulating in the information store. Also, design a redundant MTA path so that messages keep flowing if a link outage occurs. It is important that MTAs be able to keep up with the traffic that flows through them. Because it takes considerably more time to process messages from the information store than it does from memory, it is important to keep messages in the information store to a minimum to ensure timely message delivery.
