A catch-all feature that is activated for a particular e-mailbox will permit you to receive email messages that are sent to addresses that do not really exist. To put it differently, if you disable an email address and somebody still sends an email message to it, or to any miswritten email address under the exact same domain name, 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, which could be vital in case you run a company, for instance. Since you may start receiving spam, you can combine the catch-all option with anti-spam filters in order to receive only authentic messages in your inbox. Just one single mailbox per domain name can be a catch-all one and email forwarding cannot be activated for a catch-all mailbox.
