This doesn't sound like an Activiti problem … you are doing al the email sending yourself here…

I want send a Mail Task. My Listener Task will be executed when Mail task was created. when i executed my project, I can't find any exception in my console and I don't receive anything in my email box. I attached my bpm diagram.

Hi Amani.

I did not find any error in your process definition.
Questions:
# Did you try to debug it?
# Do you have a jUnit test?

Hi Amani,

Based on our experience, sending emails directly from within the workflow (using Mail Task or bespoke TaskDelegate) seems to be a Very Bad Idea. For starters, you may not want the workflow to wait for the whole SMTP interaction (especially if there's a user waiting for the workflow to proceed), and what you definitely don't want is to the whole workflow to fail due to some silly SMTP error - not to mention MailTask's templating support being quite limited.
What we ended up doing was dumping all process variables to external service that would enqueue the email and return immediately. External task executor then would get the variables through the proper template engine (Velocity, Freemarker - or Jinja2 in our case since we have external web services built in Python and running on Google App Engine) and actually send the email through.

@ekolesnikov: I would agree with that, specially in an enterprise setting that seems wise.
