Logback SMTPAppender不发送电子邮件 [英] Logback SMTPAppender not sending email

问题描述

我正在尝试使用Logback登录我的java应用程序。我相信我已经正确配置了它，但是当记录错误时

I am attempting to use Logback for logging in my java application. I believe I have it correctly configured, but when an error is logged

ch.qos.logback.classic.net.SMTPAppender中的INFO [电子邮件] - 即将发送
发送SMTP邮件Testing Main至[[e-mail]]

INFO in ch.qos.logback.classic.net.SMTPAppender[EMAIL] - About to send out SMTP message "Testing Main" to [[e-mail]]

已打印在控制台之后，之后没有打印任何其他内容，并且从未收到电子邮件。如果我在配置中输入了无效的smtp主机或用户名/密码，则在尝试发送时会立即失败，因此它正在建立连接。

is printed to the console, nothing else is printed after that, and the email is never received. If I enter an invalid smtp host or username/password in the config it fails immediately on attempting to send, so it is establishing a connection.

这是正在运行以生成测试错误的代码

This is the code that is running to produce my test errors

logger.error("Entering app");
logger.error("exiting app");

System.out.println("exiting");

任何有助于调试此问题的帮助都将非常感谢
谢谢

Any help debugging this issue would be greatly appreciated Thank you

推荐答案

这似乎是我使用的SMTP服务器的一个问题。我将Papercut设置为本地smtp服务器，我可以看到它收到消息

It seems to have been an issue with the SMTP server I was using. I setup Papercut as a local smtp server and I can see it receive the messages
