Answer 1

in a shorter, revised version of the Saurabh post, you can simply:

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl" p:host="smtp.gmail.com"
    p:port="587" p:username="[e-mail]" p:password="aSmartPassWord">
    <property name="javaMailProperties">
        <props>
            <prop key="mail.smtp.auth">true</prop>
            <prop key="mail.smtp.starttls.enable">true</prop>
            <prop key="mail.smtp.timeout">8500</prop>
        </props>
    </property>
</bean>

As far as I know, GMail only supports encrypted SMTP, and the error message tells you that this is a pretty workaround. You need to configure Spring to use this instead of plaintext SMTP.

:

Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
sender.setJavaMailProperties(props);
