How to configure Spring JavaMailSenderImpl for Gmail

Question

I am trying to find the correct properties to use to connect to the Gmail SMTP sever using the JavaMailSenderImpl class.

Let me first say that I have tried the approach found here. This worked fine. But when I tried the configuration below that post with the exact same authentication information I received a javax.mail.AuthenticationFailedException.

My currently configuration looks like this.

<bean id="mailSender" class ="org.springframework.mail.javamail.JavaMailSenderImpl" >     <property name="username" value="[email protected]" />     <property name="password" value="XXX" />     <property name="javaMailProperties">     <props>         <prop key="mail.smtp.host">smtp.gmail.com</prop>         <prop key="mail.smtp.port">587</prop>         <prop key="mail.smtp.auth">true</prop>         <prop key="mail.smtp.starttls.enable">true</prop>     </props>     </property> </bean> 

Why am I still getting this javax.mail.AuthenticationFailedException if I know that my credentials are correct.

Update

Here is my updated code based on the answers below. I am still receiving the same exception.

<bean id="mailSender" class ="org.springframework.mail.javamail.JavaMailSenderImpl" >     <property name="username" value="[email protected]" />     <property name="password" value="XXX" />     <property name="javaMailProperties">     <props>         <prop key="mail.smtp.from">[email protected]</prop>         <prop key="mail.smtp.user">[email protected]</prop>         <prop key="mail.smtp.password">XXX</prop>         <prop key="mail.smtp.host">smtp.gmail.com</prop>         <prop key="mail.smtp.port">587</prop>         <prop key="mail.smtp.auth">true</prop>         <prop key="mail.smtp.starttls.enable">true</prop>     </props>     </property> </bean> 

Answer 1

This worked for me:

        <property name="host"><value>smtp.gmail.com</value></property>         <property name="port"><value>587</value></property>         <property name="protocol"><value>smtp</value></property>         <property name="username"><value>${mail.username}</value></property>         <property name="password"><value>${mail.password}</value></property>         <property name="javaMailProperties">             <props>                 <prop key="mail.smtp.auth">true</prop>                 <prop key="mail.smtp.starttls.enable">true</prop>                 <prop key="mail.smtp.quitwait">false</prop>             </props>         </property> 

The real trick for me turned out to be that the "protocol" value has to be "smtp" (not "smtps").
