sending email from SpringBoot 2.1.3.RELEASE

I want to send an email from SpringBoot 2.1.3.RELEASE; I have defibed those properties:

spring.mail.host=smtp.gmail.com
spring.mail.username=nunito.calzada@gmail.com
spring.mail.password=aMdwd3cded2@
spring.mail.properties.mail.smtp.auth = true
spring.mail.properties.mail.smtp.socketFactory.port = 465
spring.mail.properties.mail.smtp.socketFactory.class = javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.smtp.socketFactory.fallback = false
spring.mail.propertirs.mail.smtp.ssl.enable = true
and using org.springframework.mail.MailSender

I am sending the email using org.springframework.mail.MailSender

    mailSender.send(mailMessage);

Everything seems to be OK, I don't see any exception, any error, but I don't receive email, not even in the SPAM email

I also tried

spring.mail.properties.mail.smtp.socketFactory.port = 587

with the same result

Solution

for Spring Boot add the dependency

 <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
        <version>2.1.3.RELEASE</version>
 </dependency>

Once the dependency is in place, the next step is to specify the mail server properties in the application.properties file using the spring.mail.* namespace.

For example, the properties for Gmail SMTP Server can be specified as:

spring.mail.protocol=smtp
spring.mail.host: smtp.gmail.com
spring.mail.port: 465
spring.mail.username: <user name>
spring.mail.password: <password>
spring.mail.properties.mail.smtp.auth: true
spring.mail.properties.mail.smtp.starttls.enable: true
mail.smtp.starttls.enable=false
spring.mail.properties.mail.smtp.starttls.required: true
spring.mail.properties.mail.smtp.ssl.enable = true
spring.mail.test-connection=

CODE:

@Autowired
private JavaMailSender 
private void setMailDetailsForSend( final String payload, final String email ) throws MessagingException
{

    final MimeMessage mail = mailSender.createMimeMessage();
    final MimeMessageHelper helper = new MimeMessageHelper( mail, true );
    helper.setTo( email );
    helper.setSubject( "Notification" );
    helper.setText( "text/html", payload );
    mailSender.send( mail );

}

Some SMTP servers require a TLS connection, so the property spring.mail.properties.mail.smtp.starttls.enable is used to enable a TLS-protected connection.
