1、邮件发送程序运行时报超时，但是ping smtp.163.com是OK的。org.springframework.mail.MailSendException: Mail server connection failed; nested exception is com.sun.mail.util.MailConnectException: Couldn't connect to host, port: smtp.163.com, 25; timeout -1; nested exception is: java.net.ConnectException: Connection timed out (Connection timed out). Failed messages: com.sun.mail.util.MailConnectException: Couldn't connect to host, port: smtp.163.com, 25; timeout -1;nested exception is: java.net.ConnectException: Connection timed out (Connection timed out); message exception details (1) are:Failed message 1:com.sun.mail.util.MailConnectException: Couldn't connect to host, port: smtp.163.com, 25; timeout -1; nested exception is: java.net.ConnectException: Connection timed out (Connection timed out)2、本地电脑运行正常可以发送邮件，但是部署到ecs服务器上运行就提示超时，ecs防火墙有拦截吗？ |
