A catch-all feature that is enabled for a specific email mailbox will allow you to receive email messages that are sent to email addresses that do not really exist. Otherwise said, if you delete an email address and somebody still sends an email message to it, or to any mistyped email address under the exact same domain, you’ll receive the email in the catch-all mailbox. Using this feature implies that you won’t miss an email for any reason whatsoever, which could be essential if you run a company, for instance. Since you may start receiving unsolicited bulk messages, you can combine the catch-all functionality with anti-spam filters in order to get only authentic emails in your inbox. Just one mailbox per domain can be a catch-all one and email forwarding cannot be activated for a catch-all mailbox.
