A catch-all functionality that is activated for a particular e-mailbox will allow you to receive emails that are sent to email addresses that do not really exist. In other words, if you disable an email address and someone still sends an email message to it, or to any misspelled address under the exact same domain name, you’ll get the message in the catch-all mailbox. Using this functionality means that you won’t miss an email for any reason, which could be vital in case you run a business, for instance. Since you may begin receiving unsolicited emails, you can combine the catch-all functionality with anti-spam filters in order to receive only authentic emails 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.
