Graymail refers to solicited bulk email messages that are not spam. Hosted Email Security detects marketing messages and newsletters, social network notifications, and forum notifications as graymail messages.
The Spam, Phishing, Graymail, Web Reputation, or Social engineering attack criteria allow you to create rules that take actions on these types of potentially unwanted messages.
Hosted Email Security does not apply content-based heuristic spam, BEC, phishing, graymail, Web reputation, or social engineering attack rules to email messages received from email addresses and domains listed on the Approved Senders screen.
