A catch-all email mailbox receives messages sent to inactive addresses under the very same domain name. For instance, an email message sent to the mistyped suport@domain.com will be delivered to support@domain.com if the catch-all feature has been enabled for the latter. In this way, you can receive messages from partners or customers who may have sent a message to your email address with a spelling mistake or to an outdated one, which they may still have, but you have already deactivated.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 mailbox per domain name can be a catch-all one and email forwarding cannot be activated for such a mailbox. This is due to the fact that at a certain moment you may begin receiving spam email messages in the catch-all mailbox and the forwarding restriction means that the spam will not be re-sent to a 3rd-party mailbox.
