I've been working on a custom workflow action. I am able to deploy the action and create a workflow. When I run the workflow, the code in the execute portion of the activity is not executed. I am receiving no errors in my logs except that the from address and reply to address have not been configured and that I need to set this up in central admin. Does this mean that I must set up a SMTP server in my global settings to even execute a workflow, even if the workflow has no email action? I'm guessing this is the case as I'd expect to receive an error of some sort about my action's code, if it were failing somewhere.
Thanks in advance for any help.
