I have a workflow, which is set to run when an item in a list is created. The list is email enabled, and is populated only by email.
When I send an email to the list, the workflow is not started - however if I create a new item in the list through SP the workflow starts and runs.
My environment is SP 2010 using Nintex Workflow.
This appears to be a well known problem in WSS, but I can't find anything for SP 2010 specifically.
