description The invention provides a risk mail detection method and device, computer equipment and a storage medium, and the method comprises the steps: analyzing an E-mail when it is detected that a receiving account contained in a target cluster receives the E-mail at a current moment, and obtaining a sending account which sends the E-mail; obtaining an event occurrence probability between the sending account and the receiving account; if the event occurrence probability meets a preset probability alarm threshold value, determining that the E-mail is a to-be-tested mail, and determining that a sending account sending the to-be-tested mail is a target sending account; and if the numerical value of the exchange relation between the target sending account and the target cluster meets a preset relation quantile threshold value, judging that the to-be-tested mail is a risk mail. By adopting the method, the detection accuracy of the risk mail can be effectively improved. 本申请提供一种风险邮件检测方法、装置、计算机设备及存储介质，方法包括：当检测出目标集群所含的收件账号在当前时
