A catch-all feature that is activated for a given e-mailbox will allow you to receive email messages that are sent to addresses that do not really exist. Otherwise stated, if you disable an email address and someone still sends an email message to it, or to any misspelled email address under the exact same domain, you will receive the message in the catch-all mailbox. Using this feature means that you will no longer miss an email for any reason, which could be essential in case you are running some business, for example. Since you may begin receiving unsolicited bulk messages, you can combine the catch-all option with anti-spam filtering software in order to receive only legitimate email messages in your inbox. Only one single mailbox per domain name can be a catch-all one and email forwarding cannot be activated for a catch-all mailbox.
