A catch-all email mailbox receives messages sent to nonexistent addresses under the exact same domain name. For instance, an email message sent to the miswritten email@example.com will go to firstname.lastname@example.org if the catch-all feature has been enabled for the latter. In this way, you can get email messages from pals or customers who may have sent a message to your email address with a spelling mistake or to an outdated one, which they may still have, but you have already deactivated. Just one single mailbox per domain can be a catch-all one and email forwarding cannot be activated for such a mailbox. This is due to the fact that at some point you may start receiving spam messages in the catch-all mailbox and the forwarding limitation implies that the spam will not be redirected to a third-party mailbox.
