Stopping service task after calling camunda-bpm-mail

Hello,

Now I’m trying to use camunda-bpm-mail according to the following page.

My bpmn file is as attached. For uploading, I changed value of “to” of Input parameter. Actually I input my correct mail address there.
sendmailtest.bpmn (3.5 KB)
And I’m using Camunda Full Distribution for Apache Tomcat (7.10).

After setup and starting process, I got Incident of “can’t find class” or “can’t find connector-id” in Camunda Cockpit at first. This was solved after restarting Tomcat Service.

Then, I got “Could not find mail-config on classpath…” on Incident tab. This was solved after moving mail-config.properties file to \Apache-tomcat\lib.

Then, I got “Caused by: com.sun.mail.smtp.SMTPSendFailedException: 550 5.7.60 SMTP; Client does not have permissions to send as this sender”. This was solved by changing credentials in mail-config.properties.

Now any incidents are not happen when I start process. But email is not sent to me and process instance is still in service task… I don’t know what happen and where should be checked.

Thank you in advance,
