com.sun.mail.smtp.SMTPAddressFailedException

Question

I'm trying to generate and send an automatic mail with Spring.

I have this exception when try to send email:

org.springframework.mail.MailSendException: Failed messages: javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
com.sun.mail.smtp.SMTPAddressFailedException: 550 5.1.8 <Gaetano@ConseltiGT>: Sender address rejected: Domain not found
; message exception details (1) are:
Failed message 1:
javax.mail.SendFailedException: Invalid Addresses;

Within the application-context.xml file, I have:

    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"
    p:host="${email.account.host}" p:port="${email.account.port}"
    p:username="${email.account.username}" p:password="${email.account.password}"
    p:javaMailProperties-ref="javaMailProperties"/>

<util:properties id="javaMailProperties">
    <prop key="mail.smtp.auth">${email.account.smtp.auth}</prop>
    <prop key="mail.smtp.starttls.enable">${email.account.smtp.starttls.enable}</prop>
</util:properties>

Within the service I have:

  @Service
  @Slf4j
  public class EmailSenderTUService {

@Autowired
private JavaMailSender mailSender;

private String messageDefault = "Il sistema TESORERIA UNICA TELEMATICA richiede attenzione\n";


public void sendMail(String subj, String msg) {
    MimeMessage message = mailSender.createMimeMessage();
    MimeMessageHelper helper = new MimeMessageHelper(message);
    try {
        helper.setTo("[email protected]");
        helper.setSubject(subj);
        helper.setText(messageDefault + msg);
    } catch (MessagingException e) {
        log.error("ERRORE Invio email", e);
    }
    mailSender.send(message);
}

}

Suggestions?

Solution

It seems to me that the entered Gaetano@ConseltiGT address is not valid, probably because of a typo. I would have expected it to be something like this: [email protected] or some other extension so that the domain can actually get resolved.
