The Email config properties, I use yahoo as host:

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

The part of the implementation which send the email;

@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);

Can someone help me?

Answer 1

What version of JavaMail are you using? Can you capture the debug output ? The mail server is complaining about the SMTP MAIL FROM command, which probably means the From address of your message isn't set correctly. Since you don't seem to be setting it explicitly, perhaps SimpleMailMessage is choosing a default that's bad? Setting it explicitly to a legal value will probably solve the problem.
