A catch-all feature that is enabled for a specific e-mailbox will permit you to receive emails that are sent to email addresses that do not actually exist. In other words, if you remove an email address and somebody still sends an email message to it, or to any mistyped address under the very same domain, you’ll get the email in the catch-all mailbox. Using this functionality means that you won’t miss an email for any reason whatsoever, which could be vital if you are running a business, for example. Since you may start receiving unsolicited bulk messages, you can use the catch-all option with email filters so as to receive only authentic emails in your inbox. Only one mailbox per domain can be a catch-all one and email forwarding cannot be activated for a catch-all mailbox.
