A catch-all functionality that is enabled for a certain e-mailbox will permit you to receive email messages that are sent to addresses that do not actually exist. Otherwise said, if you remove an email address and somebody still sends an email message to it, or to any miswritten address under the exact same domain name, you’ll receive the email in the catch-all mailbox. Using this feature implies that you will no longer miss an email for any reason whatsoever, which could be essential in case you are running some company, for instance. Since you may start receiving unsolicited bulk emails, you can use the catch-all option with anti-spam filtering software in order to receive only legitimate 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.
