A catch-all feature that is activated for a given email mailbox will permit you to receive emails that are sent to email addresses that do not really exist. Otherwise stated, if you remove an email address and someone still sends an email to it, or to any miswritten email address under the same domain name, you’ll receive the email in the catch-all mailbox. Using this feature implies that you won’t miss an email for any reason whatsoever, which could be vital in case you run a company, for example. Since you may begin receiving unsolicited messages, you can use the catch-all option with anti-spam filters in order to receive only authentic email messages in your inbox. Only one single mailbox per domain can be a catch-all one and email forwarding cannot be activated for a catch-all mailbox.
