邮件服务--Could not connect to SMTP host: smtp.163.com, port: 25;部署服务器:阿里云 ECS

[zhangdechang]

Please answer some questions before submitting your issue. Thanks!

版本

版本应该是1.7的,不过看过1.8最新的,相关邮件服务也是没有这段代码

问题描述

环境:阿里云ecs,企业邮箱smtp.qiye.163.com 原因:前几天运维突然告知邮件服务25端口关闭,启用465端口.需修改xxl-job-admin.properties配置文件中的xxl.job.mail.port=465, 问题:启动项目后发现,该邮件服务仍读取邮件端口25,但相对应的端口465已经读取到

此段代码中的port已经是465,但服务仍然报错,如图

真实原因是:ECS基于安全考虑，目前已禁用25端口。且服务器勾选SSL，使用465端口。 解决:参考CSDN博主:daqi1983的分享http://blog.csdn.net/daqi1983/article/details/73369440, 在邮件工具类中添加如下代码解决:

我也遇到了相同的问题 xxl-job-admin/src/main/resources/xxl-job-admin.properties的配置为(邮箱用户名和密码隐藏了)

### xxl-job email
xxl.job.mail.host=smtp.mxhichina.com
xxl.job.mail.port=465
xxl.job.mail.ssl=true
xxl.job.mail.username=x@xxx
xxl.job.mail.password=xxx
xxl.job.mail.sendNick=《任务调度平台XXL-JOB》

把executor的进程停止后，失败的时候发邮件报错

@xuxueli 我想应该是要修改xxl-job里发邮件的代码，把socketFactory的配置加上

[zhaoydo]

用props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 报错：unable to find valid certification path to requested target 查了一下需要生成证书，可以这样修改来忽略:

MailSSLSocketFactory sf = null;
                try {
                    sf = new MailSSLSocketFactory();
                } catch (GeneralSecurityException e) {
                    logger.error("error", e);
                }
                sf.setTrustAllHosts(true);
                pro.put("mail.smtp.ssl.enable", "true");
                pro.put("mail.smtp.ssl.socketFactory", sf);

[junit]

开启SSL，在application.properties中增加以下配置即可

spring.mail.properties.mail.smtp.ssl.enable=true
spring.mail.properties.mail.smtp.ssl.socketFactory=javax.net.ssl.SSLSocketFactory
