What happens when my Email Security license is suspended or deleted?
The following article describes the behaviour if your Email Security license is suspended or deleted.
Mail flow will continue however any customer defined or standard rules will be disabled, meaning spam and potentially malicious email will be delivered to your mail server. The (Locked) rules will remain active along with the Deliver rule, to ensure mail flows correctly.
Mail flow will be interrupted. You should ensure that your domain MX records are updated to point to a different SMTP service for continued mail flow.
