A catch-all feature that is enabled for a specific email mailbox will permit you to receive emails that are sent to addresses that do not actually exist. Otherwise stated, if you remove an email address and somebody still sends a message to it, or to any mistyped email address under the very same domain, you will get 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 vital in case you run some company, for example. Since you may start receiving unsolicited bulk emails, you can combine the catch-all option with email filters so as to get only legitimate email messages in your inbox. Only one mailbox per domain name can be a catch-all one and email forwarding cannot be activated for a catch-all mailbox.
