I have created an email notification workflow in K2 designer in K2 VM server, and i have tried with the following id's

1. administrator@denalix.com

2. x@gmail.com

3. Official ID

Workflow triggerd and the status also updated, but  i didn't receive any email notification for the above id's.  

Can anyone guide me how to configure the email and how to view the flow of the workflow?

Thanks,

Lakshmi
