How to Send and Recieve Emails from WSO2 ESB

How to Send an Email From WSO2 ESB

1. Configure email transport in <ESB_HOME>/repository/conf/axis2/axis2.xml/axis2.xml (There is transportsender commented out in default axis2.xml. You can uncomment them and change the parameter values as you wanted.)

<transportsender class="org.apache.axis2.transport.mail.MailTransportSender" name="mailto">  
     <parameter name="mail.smtp.host">smtp.gmail.com</parameter>  
     <parameter name="mail.smtp.port">587</parameter>  
     <parameter name="mail.smtp.starttls.enable">true</parameter>  
     <parameter name="mail.smtp.auth">true</parameter>  
     <parameter name="mail.smtp.user">sender</parameter>  
     <parameter name="mail.smtp.password">password</parameter>  
     <parameter name="mail.smtp.from">sender@gmail.com</parameter>  
   </transportsender>

2. If ESB has already started, restart the server.

3. Log in to Management console and add below proxy.

<?xml version="1.0" encoding="UTF-8"?>  
 <proxy xmlns="http://ws.apache.org/ns/synapse"  
     name="EmailSender"  
     startOnLoad="true"  
     statistics="disable"  
     trace="disable"  
     transports="https,http">  
   <target>  
    <inSequence>  
      <log/>  
      <send>  
       <endpoint>  
         <address uri="http://www.mocky.io/v2/57cef5e5260000ab0564fefa"/>  
       </endpoint>  
      </send>  
      <property name="messageType"  
           scope="axis2"  
           type="STRING"  
           value="text/html"/>  
      <property name="ContentType" scope="axis2" value="text/html"/>  
      <property name="Subject" scope="transport" value="ESB"/>  
      <property name="OUT_ONLY" value="true"/>  
      <property name="FORCE_SC_ACCEPTED" scope="axis2" value="true"/>  
      <send>  
       <endpoint>  
         <address uri="mailto:reciever@gmail.com"/>  
       </endpoint>  
      </send>  
    </inSequence>  
    <outSequence/>  
   </target>  
   <description/>  
 </proxy>

4. Invoke the proxy and then you can see a mail in reciever@gmail.com's inbox from sender@gmail.com

      <drop/>  
    </inSequence>  
    <outSequence>  
      <send/>

   </target>  
   <parameter name="transport.PollInterval">5</parameter>  
   <parameter name="mail.pop3.host">pop.gmail.com</parameter>  
   <parameter name="mail.pop3.password">wso2pass</parameter>
