Email redirection is a process in which incoming emails sent to one email address are automatically forwarded to another designated address. This ensures that messages reach the intended recipient even if the original address is inactive, has changed, or is managed by someone else. Email redirection is commonly used during employee transitions, organizational changes, or when consolidating multiple email accounts. It helps maintain communication continuity, prevents loss of important messages, and can also be used as part of security measures to monitor or archive emails. Proper configuration is essential to avoid unauthorized access or data leakage.
