I am sending mail via a scheduler job.

Create a scheduler definition xml file. Look for "ir_cron_scheduler_action" in the code for an example.

In the model definition py file create a function "run_scheduler" def run_scheduler(self, cr, uid, automatic=False, use_new_cursor=False, context=None): # Create mail body etc. Then call: mail_obj.schedule_with_attach(params)

Hope this helps
