A catch-all feature that is enabled for a given e-mailbox will permit you to receive email messages that are sent to addresses that do not really exist. In other words, if you deactivate an email address and somebody still sends an email message to it, or to any mistyped email address under the very same domain name, you’ll receive the message in the catch-all mailbox. Using this feature means that you will no longer miss an email for any reason whatsoever, which could be essential in case you are running a company, for instance. Since you may start receiving junk email messages, you can use the catch-all functionality with anti-spam filtering software so as to get only authentic 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.
