A catch-all feature that is enabled for a given e-mailbox will allow you to receive email messages that are sent to addresses that do not really exist. Otherwise stated, if you delete an email address and someone still sends an email to it, or to any miswritten address under the exact same domain name, you’ll receive the email in the catch-all mailbox. Using this functionality implies that you won’t miss an email for any reason whatsoever, which could be crucial in case you run some company, for instance. Since you may begin receiving junk email messages, you can use the catch-all feature with email filters in order to receive only legitimate email messages in your inbox. Only one single mailbox per domain can be a catch-all one and email forwarding cannot be enabled for a catch-all mailbox.
