【问题描述】：

我尝试使用 javaMail、spring-boot 和 yahoo 发送电子邮件。我得到了这个 SMTPSendFailedException，我不知道为什么。

这里有一部分例外：

ErrorPageFilter: Forwarding to error page from request [/registration] due to exception [Failed messages: com.sun.mail.smtp.SMTPSendFailedException: 501 Syntax error in arguments

  nested exception is:

Email 配置属性，我使用 yahoo 作为主机：

spring.mail.host=smtp.mail.yahoo.com
spring.mail.port=465
spring.mail.username=*****@yahoo.com
spring.mail.password=*****
spring.mail.default-encoding=UTF-8
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.ssl.enable=true

发送电子邮件的实现部分；

@Autowired
JavaMailSender javaMailSender;


    String recipientAddress = XXXX.getUser().getEmail();
    String subject = "Bienvenue chez AAAA";
    String message = "huhuu";
    SimpleMailMessage email = new SimpleMailMessage();
    email.setTo(recipientAddress);
    email.setSubject(subject);
    email.setText(message + "\n");
    javaMailSender.send(email);

有人可以帮我吗？

【解决方案1】：

您使用的是什么版本的 JavaMail？你能捕捉到debug output 吗？邮件服务器抱怨 SMTP MAIL FROM 命令，这可能意味着您的邮件的发件人地址设置不正确。由于您似乎没有明确设置它，也许 SimpleMailMessage 选择了一个不好的默认值？将其显式设置为合法值可能会解决问题。
