A catch-all functionality that is activated for a certain e-mailbox will allow you to receive email messages that are sent to addresses that do not really exist. To state it differently, if you delete an email address and someone still sends an email to it, or to any mistyped email address under the exact same domain name, you will receive the message in the catch-all mailbox. Using this functionality implies that you won’t miss an email for any reason, which could be crucial in case you run a company, for instance. Since you may begin receiving unsolicited emails, you can use the catch-all feature with anti-spam filters so as to receive only real emails in your inbox. Just one single mailbox per domain name can be a catch-all one and email forwarding cannot be enabled for a catch-all mailbox.
