email - Jenkins 电子邮件插件 : Could not connect to SMTP host: smtp. gmail.com，端口:465；

Question

我正在尝试为 Jenkins 构建作业配置电子邮件通知(使用 Mailer 插件)。我在 TomEE 中使用 Jenkins。当我尝试测试我的配置时，我得到了 javax.mail.MessagingException:

Failed to send out e-mail

javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465;

我了解到 Jenkins 的新安全功能，它不允许向非 Jenkins 用户发送邮件。所以我再次尝试在我的 catalina.properties 中添加以下内容:

hudson.tasks.MailSender.SEND_TO_UNKNOWN_USERS=true
hudson.tasks.MailSender.SEND_TO_USERS_WITHOUT_READ=true

我仍然遇到同样的错误。

任何帮助都会很棒。谢谢。

Answer 1

配置电子邮件服务有时会有点麻烦，所以一旦您遇到我遇到的一些烦人的问题:

javax. mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465;

或者

javax.mail.AuthenticationFailedException: 535-5.7.8 Username and Password not accepted

如果您遇到其中一个问题，很可能是您没有允许您的电子邮件发件人通过此服务发送电子邮件，因此您所要做的就是登录您的发件人电子邮件，然后转到 Mail设置 -> 安全 -> 启用不太安全的应用程序访问

Click on Turn on access(not recommended) then turn it on

此外，请确保您输入了正确的电子邮件和密码，选中使用SSL并确保SMTP端口 是 465。

如果错误仍然存​​在，那么它一定是与您的防火墙有关，阻止您使用 Jenkins 发送 SMTP 请求，所以要暂时解决这个问题，我所要做的就是禁用我的 Avast 杀毒软件小时并测试配置，它工作得很好。

如果您有任何问题，请随时对此答案发表评论，我很乐意为您提供帮助
