Abstract
A method, system, and computer-usable medium are disclosed for establishing a reference outbound email volume rate for a user account, monitoring the user account to determine a current outbound email volume rate, determining a risk score based on the current outbound email volume rate and the reference outbound email volume rate, buffering outgoing emails of the user account if the risk score exceeds a threshold risk score, analyzing the buffered emails against one or more factors indicative of a probability of the buffered emails comprising spam, and responsive to analysis of the buffered emails against the one or more factors indicating that the user account is potentially compromised, quarantine the user account and prevent outbound mail from being delivered from the user account.
