Symantec has conducted a health audit in advance of a planned infrastructure change, and has found that you are not fully configured per our Email Security.cloud best practice requirements to accept SMTP (port 25) email traffic from Symantec published global IP ranges.

In order to avoid any service disruption with email traffic delivery, please take the following actions:

1. Make sure you are allowing Symantec.Cloud IP ranges listed here for successful traffic delivery.
2. Ensure your firewall policies are also configured to allow outbound email delivery to the same IP ranges.
