A catch-all feature that is activated for a specific e-mailbox will allow you to receive emails that are sent to addresses that do not really exist. Otherwise stated, if you disable an email address and someone still sends a message to it, or to any miswritten address under the exact same domain, you will receive the email in the catch-all mailbox. Using this feature means that you won’t miss an email for any reason whatsoever, which could be vital in case you run some business, for example. Since you may start receiving unsolicited messages, you can combine the catch-all functionality with anti-spam filters so as to receive only authentic emails in your inbox. Only one single mailbox per domain can be a catch-all one and email forwarding cannot be activated for a catch-all mailbox.
