Zoho Mail Delivery Incident Checklist

Trace the affected Zoho Mail path

Review the Zoho Mail status page before changing DNS or mail routing.

• Compare webmail login, sending, receiving, and IMAP access.
• Check message queues and bounce codes for the affected domain.
• Record data-center region and timestamps without sharing message content.

Do not alter MX records during a suspected transient outage without a planned rollback.
