A catch-all functionality that is activated for a specific e-mailbox will allow you to receive emails that are sent to email addresses that do not really exist. In other words, if you delete an email address and someone still sends an email message to it, or to any miswritten address under the very same domain name, you’ll 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 if you run some company, for example. Since you may start receiving spam email messages, you can combine the catch-all feature with anti-spam filtering software in order to get only real messages in your inbox. Just one mailbox per domain can be a catch-all one and email forwarding cannot be enabled for a catch-all mailbox.
