A catch-all feature that is activated for a certain e-mailbox will permit you to receive email messages that are sent to email addresses that do not really exist. To put it differently, if you delete an email address and somebody still sends a message to it, or to any miswritten email address under the same domain name, you will receive the email in the catch-all mailbox. Using this functionality means that you will no longer miss an email for any reason whatsoever, 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 option with anti-spam filters in order to receive only authentic email 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.
