If I configure my formset to have multiple recipients in the to: field, the email sending process fails. The input is written to file, but the email is not sent. Raven doesn't get past $this->send($submission, $config);. Consequently, the on_success hook never runs and the flash is not set so the raven variables don't come through correctly.

Here is an example of a failing yaml file:

email:
  to: [email protected], [email protected]
  from: [email protected]
  subject: A form has been submitted
  automagic: true
