A catch-all functionality that is enabled for a certain e-mailbox will allow you to receive email messages that are sent to addresses that do not really exist. In other words, if you disable an email address and somebody still sends an email message to it, or to any mistyped address under the same domain, you will 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 if you are running a company, for instance. Since you may start receiving junk emails, you can combine the catch-all feature with anti-spam filtering software so as to get only authentic email messages in your inbox. Just one single mailbox per domain name can be a catch-all one and email forwarding cannot be activated for a catch-all mailbox.
