I am trying to configure the email notification bit for WSO2 EMM and I've been having problem with it. I followed the instruction give here to go to
<EMM_HOME>/repository/conf/axis2/axis2.xml` and do this
<transportSender name="mailto" class="org.apache.axis2.transport.mail.MailTransportSender">
<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">synapse.demo.0</parameter>
<parameter name="mail.smtp.password">mailpassword</parameter>
<parameter name="mail.smtp.from">synapse.demo.0@gmail.com</parameter>
</transportSender>
As Directed Here and then, I kept getting this error
[2016-05-08 09:39:42,800] ERROR {org.wso2.carbon.email.sender.core.service.EmailSenderServiceImpl} - Error occurred while delivering the message, subject: 'You have successfully been registered in WSO2 EMM', to: 'sososo@gmail.com'
