A catch-all feature that is enabled for a certain e-mailbox will allow you to receive email messages that are sent to email addresses that do not really exist. To put it differently, if you deactivate an email address and someone still sends a message to it, or to any misspelled email address under the same domain name, you will get the message in the catch-all mailbox. Using this functionality means that you won’t miss an email for any reason whatsoever, which could be vital in case you are running some company, for instance. Since you may start receiving unsolicited email messages, you can combine the catch-all functionality with email filters so as to get only legitimate messages in your inbox. Only one mailbox per domain name can be a catch-all one and email forwarding cannot be set up for a catch-all mailbox.
