Hii Camunda,
i’m new in camunda BPMN.yesterday i created a workflow for sending mail to some person.but the process got stuck on the service task.i’m using linux machine for development purpose**.my question is there any port need to open for sending mail or which port camunda is using for sending mail.**

Hi @Lalit_Verma

It’s hard to now exactly what could be wrong with more information.

  • Your model
  • The code you’re running
  • The specific error as it occurs in the logs
  • Any changes to the default configurations you might be making.


Based on your last sentence, you stated that it’s Linux machine. you can check target mail server(smtp server with port) using telnet.
