                + "&delete=true"
                + "&consumer.delay=" + delay
                + "&mail.imap.ssl.trust=" + emailHost
                + "&disconnect=false&closeFolder=false")

异常可能意味着客户端有一段时间没有发送任何命令，然后服务器关闭了连接。如果从你的观点来看这是合理的，那好吧。如果没有，您必须显示协议日志以进一步分析。我仅从客户端获得此异常。您的意思是客户端收到服务器未发送的

BYE

？这就是异常日志中的内容。请参阅我在描述中发布的日志。protocolConnect上的SocketTimeoutException可能意味着它无法连接到服务器，可能是由于防火墙。
