A catch-all feature that is activated for a certain e-mailbox will permit you to receive emails that are sent to addresses that do not really exist. Otherwise put, if you remove an email address and someone still sends an email to it, or to any mistyped email address under the same domain, you’ll receive the email in the catch-all mailbox. Using this feature means that you will no longer miss an email for any reason whatsoever, which could be vital if you are running a company, for instance. Since you may begin receiving junk emails, you can use the catch-all functionality with anti-spam filtering software so as to get only real email messages in your inbox. Only one mailbox per domain name can be a catch-all one and email forwarding cannot be enabled for a catch-all mailbox.
