The reasons the company gives
The company's own explanation, not something inferred from the numbers.As the incidence of spoofed emails and phishing attacks has increased, the change is intended to reduce customers' risk of encountering fraudulent emails and further enhance security. To avoid legitimate emails being incorrectly classified under a stricter policy, Zaif has been monitoring and adjusting email delivery under the previous monitoring setting.
