A high volume of notification or undelivered emails may cause our BEMTA servers delivery queues to build. This backlog leads to delivery latency for legitimate mail traffic.
A proactive case will be logged by support engineer, and an email notification will be sent with subject High BEMTA QUEUES or High MAIL QUEUES along with other details:
Domain name :
Domain queue count :
Domain queue:
Email Security.cloud
The delayed queue is caused by a high volume of automated notification or undelivered emails from a specific customer or third-party service that overwhelms the processing capacity of the regional delivery nodes.
Due to the high volume of email count that cannot be delivered, Email Security Cloud Support Team is requesting assistance from your organization to investigate your local email server or 3rd party services.
The sample error and so as email headers require reviewing to ensure the legitimacy of the emails. If those emails are not legitimate, a written confirmation is required so purging can be initiated.
Additionally, please provide confirmation if the root cause has been addressed to prevent any recurrences.
