I've run into this two times now, where a forms process is provided a bad email and then proceeds to show as suspended but sends many many copies of the email so any poor soul cc'd on the email gets their inbox crushed mercilessly.
The process shows as suspended so I haven't been able to figure out why it is still sending emails.
Is there a way to avoid this happening when an employee enters an invalid email address?
Is this related to us using an offsite email service, with an on-prem Forms server?
