A catch-all functionality that is enabled for a specific e-mailbox will permit you to receive email messages that are sent to addresses that do not really exist. Otherwise stated, if you deactivate an email address and somebody still sends an email to it, or to any misspelled address under the same domain name, you’ll receive the email in the catch-all mailbox. Using this feature implies that you won’t miss an email for any reason, which could be vital in case you run a business, for instance. Since you may start receiving unsolicited bulk emails, you can combine the catch-all feature with email filters so as to get only real emails 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.
