How do I recover a sanitized email intact? Author: Luis Fernandes July 11, 2020 13:20 AnswerSanitized messages cannot be recovered. In order to be received intact, the message will need to be resent after modifying the filter that caught the email. Usually this is either Keyword Filtering or the HTML Sanitizer.
