Zoho Mail - Catch-All Address for Misdirected Emails

Zoho Mail introduces Catch-All Address support so messages sent to invalid or mistyped addresses within your domain are routed to a designated mailbox instead of bouncing.

• Any email sent to a non-existent or mistyped local part within the domain is delivered to the configured catch-all mailbox rather than returned to the sender.
• Admins or anyone with mailbox access can review the captured messages, identify typos or naming-format errors, and forward them to the intended recipient.
• Useful for catching everyday typos, handling naming inconsistencies such as first.last versus last.first, and supporting legacy or retired addresses without bounces.
• Preserves messages from customers, partners, and vendors who use slightly incorrect addresses, helping protect external communication.
• Reduces the value of brute-force address discovery attempts, because attackers do not receive bounce responses that reveal which local parts are valid.
• Gives admins centralised visibility of misdirected mail, making it easier to spot recurring typos and reducing the support overhead of follow-up requests for missed messages.
• To configure, log in to the Zoho Mail Admin Console, go to Domains, select the relevant domain, open Advanced Settings, Catch-all Address, enter the mailbox or group address, and click Update.
• A valid mailbox or group within the organisation is required; if one does not already exist, create a mail account or group for use as the catch-all before configuring this setting.
