A catch-all functionality that is enabled for a certain e-mailbox will allow you to receive email messages that are sent to email addresses that do not really exist. Otherwise said, if you delete an email address and somebody still sends an email to it, or to any misspelled email address under the same domain, you will get the message in the catch-all mailbox. Using this feature means that you won’t miss an email for any reason, which could be vital in case you are running some company, for instance. Since you may begin receiving spam email messages, you can combine the catch-all feature with anti-spam filters so as to get only authentic emails in your inbox. Only one mailbox per domain name can be a catch-all one and email forwarding cannot be enabled for a catch-all mailbox.
