Recieve GMail through Mailto transport -WSO2 ESB

In this Post I will explain How we can receive Emails through WSO2 ESB Mailto transport and perform some operations on it.

1. First lets Enable the transport. Open "repository/conf/axis2/axis2.xml" and uncomment the following section.

<transportReceiver name="mailto" class="org.apache.axis2.transport.mail.MailTransportListener">
        <!-- configure any optional POP3/IMAP properties
        check com.sun.mail.pop3 and com.sun.mail.imap package documentation for more details-->
    </transportReceiver>

2. Now lets create a proxy service to consumes the Emails. You can Copy and paste the following proxy service to source view to create the proxy. Make sure you change access parameters accordingly.

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="JasperEmailPOP3"
       transports="mailto"
       statistics="disable"
       trace="disable"
       startOnLoad="true">
   <target>
      <inSequence>
         <property name="senderAddress"
                   expression="get-property('transport', 'From')"
                   scope="default"
                   type="STRING"/>
         <log level="custom">
            <property name="Date" expression="$trp:Date"/>
            <property name="Subject" expression="$trp:Subject"/>
            <property name="Content-Type" expression="$trp:Content-Type"/>
            <property name="From" expression="$trp:From"/>
         </log>
         <drop/>
      </inSequence>
      <outSequence>
         <send/>
      </outSequence>
   </target>
   <parameter name="mail.pop3.socketFactory.class">javax.net.ssl.SSLSocketFactory</parameter>
   <parameter name="transport.PollInterval">5</parameter>
   <parameter name="mail.pop3.host">pop.gmail.com</parameter>
   <parameter name="mail.pop3.user">ycwso2test</parameter>
   <parameter name="transport.mail.Protocol">pop3</parameter>
   <parameter name="mail.pop3.socketFactory.port">995</parameter>
   <parameter name="transport.mail.Address">ycwso2test@gmail.com</parameter>
   <parameter name="mail.pop3.password">wso2qa123</parameter>
   <parameter name="mail.pop3.port">995</parameter>
   <parameter name="mail.pop3.socketFactory.fallback">false</parameter>
   <description/>
</proxy>

3. Now Send a Email to your Email account and you will see the following log in backlogs.

[2016-08-03 12:10:05,232]  INFO - LogMediator Date = Wed, 3 Aug 2016 12:09:25 +0530, Subject = This is a Test, Content-Type = multipart/alternative; boundary=001a11402208fef0bb0539251978, From = Yasassri Ratnayake <ycrnet@gmail.com>

So thats it. If you cannot get this to work you can enable Debug logs and check whats wrong. To do this add the following line to repository/conf/log4j.properties and restart the ESB server.

log4j.logger.org.apache.axis2.transport.mail.MailTransportListener=DEBUG
