A catch-all feature that is activated for a certain e-mailbox will permit you to receive emails that are sent to email addresses that do not actually exist. Otherwise stated, if you disable an email address and somebody still sends an email message to it, or to any mistyped email address under the very same domain, you will receive the message in the catch-all mailbox. Using this feature means that you won’t miss an email for any reason whatsoever, which could be essential if you run a business, for example. Since you may start receiving junk emails, you can combine the catch-all feature with anti-spam filters in order to get only real messages in your inbox. Just one mailbox per domain name can be a catch-all one and email forwarding cannot be set up for a catch-all mailbox.
