Notification in case email couldn't be delivered.

[Noelia Fernandez]

I'm using Jira service desk automation to send emails to Suppliers. I need to know if there is a way to know that the email couldn't be delivered because the email address wasn't right or is not available, or any other reason. I tested sending emails to fake email directions but didn't receive any warning.

To see if you have an incoming email that has failed DMARC sender verification, check your email processing logs.
