A catch-all feature that is activated for a certain e-mailbox will allow you to receive emails that are sent to email addresses that do not really exist. To state it differently, if you remove an email address and someone still sends an email to it, or to any miswritten email address under the exact same domain, you’ll receive the email in the catch-all mailbox. Using this feature means that you won’t miss an email for any reason whatsoever, which could be essential in case you are running a company, for example. Since you may start receiving unsolicited messages, you can use the catch-all option with email filters so as to receive only real messages in your inbox. Only one single mailbox per domain can be a catch-all one and email forwarding cannot be activated for a catch-all mailbox.
