E-mail Notifications 

1. First to enable sending email notifications user has to configure the mail transport in axis2.xml at GREG_HOME/repository/conf/axis2/ . Please refer this page to enable email configuration.
2. User has to provide a valid email address to receive notifications from the subscribed resource. 
   
   

3. When a subscription is added initially a verification email will be sent to the user. When user clicks the verification URL the server console would get open in a different tab prompting a successfully verified message.

   Info

   One Time Email Verification When adding subscriptions to different resources defining the same email address as the notification method, for each subscription users will receive verification email with a link to verify the subscription. The subscription will get active only if the user clicks the verification URL. But if the user starts the server as ./wso2server.sh -Donetime.email.verification=true  the email verification would only happen once when the particular email address is used for first time. Changing Host Name of URLs in Verification/Notification E-mails To change the Host Name of URLs appearing in Verification and Notification e-mails, set the HostName attribute in repository/conf/carbon.xml.

   
   

4. When ever an event occurs which is in accordance with the subscription type, user will recieve notification emails .
