Email Delivery Issue to X

This was a false alarm, there was no real problem.

We are currently experiencing issues delivering emails to a small subset of customers/recipients using service. The result is that emails are queued for delivery. Our investigation shows the issue is occurring due to throttling our IP range. As a workaround, our engineers have removed the affected IP range from production to prevent service interruption. However, any existing email will remain queued till the throttling is cleared. Please note that there is no impact to protection services, and all other aspects of our services remain functional.

We are working with to address the situation. We are requesting affected customers to open a case directly with and request rate-limiting/blacklisting to be removed as well as the IP range to be added in the global whitelist. Customers are also requested to whitelist Symantec IPs using solution.

Symantec will continue to hold emails based on standard and custom retry email schedules configured by our customers. We will provide an update at XX:XX UTC or as soon as more information becomes available.
