A catch-all functionality that is activated for a given e-mailbox will permit you to receive email messages that are sent to addresses that do not really exist. Otherwise put, if you delete an email address and somebody still sends an email message to it, or to any mistyped email address under the same domain, you’ll get the message in the catch-all mailbox. Using this feature implies that you won’t miss an email for any reason, which could be crucial in case you are running some company, for example. Since you may begin receiving unsolicited bulk emails, you can combine the catch-all option with anti-spam filters in order to receive only real 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.
