We have upgraded our test environment to a linux box and as a result the POAPPRV workflow is sending (or trying to send) emails.
The workflow gets to "Send notification to all web suppliers" and assigns the value of "Yes". In PRD, the value is "No". The test environment is an exact copy of PRD from 2 months ago and no changes have been done.
Looking at the supplier site, notification is BLANK. There is also No email address associated with the supplier site in question.
