A catch-all feature that is activated for a given email mailbox will permit you to receive email messages that are sent to addresses that do not really exist. Otherwise stated, if you disable an email address and somebody still sends a message to it, or to any misspelled address under the exact same domain, you’ll receive the email in the catch-all mailbox. Using this feature means that you won’t miss an email for any reason, which could be vital in case you are running a business, for example. Since you may begin receiving spam, you can combine the catch-all functionality with anti-spam filters in order to receive only authentic 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.
