A catch-all feature that is enabled for a given e-mailbox will permit you to receive emails that are sent to email addresses that do not actually exist. Otherwise stated, if you remove an email address and someone still sends an email to it, or to any mistyped email address under the exact same domain name, you’ll get the message in the catch-all mailbox. Using this feature implies that you will no longer miss an email for any reason, which could be essential in case you are running a company, for example. Since you may begin receiving spam, you can combine the catch-all feature with anti-spam filtering software in order to receive only authentic messages in your inbox. Only one single mailbox per domain name can be a catch-all one and email forwarding cannot be set up for a catch-all mailbox.
