1. A method of prioritizing messages, comprising: receiving one or more first incoming messages from a computer network, the incoming messages having a reputation score below a first threshold; adding the one or more first incoming messages to a receiving queue; receiving a second incoming message from the computer network, the second incoming message having a reputation score above the first threshold; determining via electronic processing circuitry that the receiving queue's content is above a capacity threshold; in response to the determination that the content is above the capacity threshold, selecting a first queued message for removal from the receiving queue based on the selected message having a reputation score below the first threshold; removing the selected message from the receiving queue; and adding the second incoming message to the receiving queue.
