A catch-all feature that is activated for a certain e-mailbox will allow you to receive email messages that are sent to addresses that do not really exist. Otherwise put, if you deactivate an email address and somebody still sends an email to it, or to any miswritten address under the exact same domain, you’ll get the email in the catch-all mailbox. Using this functionality implies that you will no longer miss an email for any reason whatsoever, which could be crucial in case you are running some business, for instance. Since you may start receiving unsolicited email messages, you can combine the catch-all option with anti-spam filtering software in order 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.
