Just getting started with BP.  Trying to use the Mail Event to send a simple email.   Can someone tell me the correct format for the From and To fields ?   I have simply pulled in a schema field containing a user id and this does not work.   I have tried other formats such as K2:domainuser that also does not work.   Task mailings do work with the InfoPath client event,  so the mail server setting seems to be correct.    Thanks.
