Sreepathia, thanks for your reply. I'm sure that the address that I am sending the email is in the mail server that I am using, because I use the specified smtp server in others applications (no jBPM applications) with the same email address that I am trying now. Would you think that is a configuration problem? Maybe with my jbpm.cfg.xml oy other thing that I didn't do? Thanks!
