Springboot admin 发送邮件失败：com.sun.mail.smtp.SMTPSenderFailedException: 553 Mail from must equal authorized user

发邮件已经是老生常谈了，今天又遇到了，而且又出了各种问题。我晕哦。

我的配置是：

spring.mail.host=smtp.163.com
spring.mail.username=klxxxx
spring.mail.password=qwer1234
spring.boot.admin.notify.mail.to=[email protected]

出现了553：

难道是密码错误吗？ 仔细确认，密码是没错的。

故意把密码设置错误，得到另外一个异常： Caused by: javax.mail.AuthenticationFailedException: 535 Error: authentication failed

密码错误确实会出现553，但是具体原因是不同的。可见， 密码是没问题的。

需要一个授权码？ 我记得163邮箱是挺好用的。qq邮箱需要授权码， 163好像不需要的吧。。

难道需要额外配置：

spring.mail.protocol=smtp
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.ssl.enable=true
spring.mail.test-connection=true

加上了，然并卵。

这坑爹啊。。 查看所有可用的配置，偶然看到了一个配置 spring.boot.admin.notify.mail.from，设置一下吧， 同 spring.mail.username=klxxxx 一样的。 重启， 好了！

Springboot admin 发送邮件失败：com.sun.mail.smtp.SMTPSenderFailedException: 553 Mail from must equal authorized user的相关文章

com.sun.mail.smtp.SMTPSendFailedException: 553 Mail from must equal authorized user

1.错误描写叙述 553 Mail from must equal authorized user com.sun.mail.smtp.SMTPSendFailedException: 553 Mail from must equal authorized user at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:1333) at com.sun.mail.smtp.SMTPTransport.mail

完美解决 javax.mail.SendFailedException: 与 com.sun.mail.smtp.SMTPAddressFailedException: 抛错

由于某个模块用到程序运行完后,自动收集结果发送邮件给相关人等. 邮件里有个地址貌似出问题,导致所有的收件人都发送不出去. 抛出的错误如下: javax.mail.SendFailedException: Invalid Addresses; nested exception is: com.sun.mail.smtp.SMTPAddressFailedException: 550 5.7.1 Unable to relay for [email protected] at com.sun.mai

python通过SMTP发送邮件失败,报错505/535
