I can't post anything with Postie

Hello, I installed Postig in my WP two days ago. The plugin was working very well, but today it stop, is implosible to publish by email. I sent some diferents mails but Postie doesn’t publish.

I tried to publish on clicking on button Process email and the others button, but mails are in my inbox and no as a post in my wordpress

When I clic in “Bebug” button this it is the result:
