Using this basic setup results in the following exception when receiving any mail:

There is an error in your Logger info call in process_email/1. You’re logging mail_info.id but there is no id field in the mail_info map.
The available keys are: [:recipients, :to, :cc, :bcc, :from, :reply_to, :subject, :has_attachment, :headers]
