A catch-all feature that is enabled for a given email mailbox will permit you to receive emails that are sent to email addresses that do not actually exist. To put it differently, if you deactivate an email address and somebody still sends an email to it, or to any mistyped address under the exact same domain name, you’ll get the email in the catch-all mailbox. Using this functionality means that you won’t miss an email for any reason, which could be essential in case you are running a business, for example. Since you may begin receiving unsolicited bulk email messages, you can combine the catch-all feature with anti-spam filtering software in order to receive only authentic email messages in your inbox. Just one mailbox per domain name can be a catch-all one and email forwarding cannot be enabled for a catch-all mailbox.
