Our Cisco C170 ESA (Version: 11.0.4-003) is randomly (apparently) ignoring some of the white listing we've put in place. We've opened a case with Cisco support, but I wanted to post on the forum as well. We only white list email addresses. Sometimes our clients will get an email from the company in their Inbox, and other times that same email address will end up in the Cisco spam quarantine. The device has been restarted FWIW.
