Adding the following mail transport configuration to the <GREG_HOME>/repository/conf/axis2/axis2.xml file, to configure WSO2 Governance Registry to send notifications via email.
<transportSender name="mailto" class="org.apache.axis2.transport.mail.MailTransportSender">
<parameter name="mail.smtp.from">synapse.demo.1@gmail.com</parameter>
<parameter name="mail.smtp.user">synapse.demo.1</parameter>
<parameter name="mail.smtp.password">mailpassword</parameter>
<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>
</transportSender>
This sends each email to the corresponding delivery address you specify in the subscription using synapse.demo.1@gmail.com as the sender. This configuration is applicable for email addresses you obtain from gmail.com. Similarly, you can use an email address of any other sender, for which the email service provider grants access to a SMTP Server.
