About JavaMailSender Authentication

Did you know that JavaMailSender is a Java class? In fact, it makes it easier to send email messages via the JavaMail API.

On the other hand, authentication helps verify the identity of a user or application before we offer it access to a system or service. When we talk about authentication in relation to JavaMailSender, it indicates the authentication required while sending email messages through an email server that requires authentication, like GMail.

Authenticating emails with JavaMailSender

According to our experts, the following properties are critical when we use authentication with JavaMailSender:

• Username:

  This indicates the sender’s email address that is used to authenticate with the email server.
• Password:

  Here, we have to specify the sender account’s password that is used to authenticate with the email server.
• SMTP Host:

  This is the IP address or the hostname of the email server that is used to send email messages.
• SMTP Port:

  The SMTP port indicuate the port number of the email server that is being used to send email messages.
• SMTP Auth:

  The SMTP Auth property is a Boolean value. It specifies if authentication is required or not by the email server.

For instance, we can easily configure JavaMailSender as seen below:

In the above example we have used the Spring Framework;s implementation. This involves creating a new instance of JavaMailSenderImpl class and setting the corresponding properties.

After configuration, we can easily send email messages via the send() method.

At the end of the day, using authentication with JavaMailSender results in a reliable and secure way to send emails, especially when we use email servers that require authentication.
