Spring Boot provides the ability to send emails via SMTP using the JavaMail Library. Here we will be illustrating step-by-step guidelines to develop Restful web services that can be used to send emails with or without attachments.

How to develop Body of email. Send email from Spring Boot Application to Outlook How Spring Boot Mail API works. Understand the Java mail API fundamentals Use HTML, CSS to create, design email

Implementation Step 1: Create a Spring Boot Web Application using Spring Initializer

Step 2: Adding the spring-boot-starter-mail dependency in pom.xml.

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

Step 3: Configure SMTP server detail in Application.properties.

    ########## SMTP configuration to send out emails ##########
    ####### Make sure to use the correct SMTP configurations #######
    spring.mail.host=mail.madarasa.com.in
    spring.mail.port=465
    [email protected]
    spring.mail.password=yourmailpassword
    
    # Other properties
    spring.mail.properties.mail.smtp.auth=true
    spring.mail.properties.mail.smtp.connectiontimeout=5000
    spring.mail.properties.mail.smtp.timeout=5000
    spring.mail.properties.mail.smtp.writetimeout=5000
    
    # TLS , port 587
    spring.mail.properties.mail.smtp.starttls.enable=true
    
    # SSL, post 465
    spring.mail.properties.mail.smtp.socketFactory.port = 465
    spring.mail.properties.mail.smtp.socketFactory.class = javax.net.ssl.SSLSocketFactory
