A catch-all mailbox is one that collects all the email messages sent to invalid addresses. For instance, if your email address is info@domain.com, but somebody mistypes it and sends a message to inof@domain.com, it will still be received in the catch-all mailbox that you have created. Only one mailbox per domain name can have this feature activated and in this way you’ll never miss emails because the other party has an outdated address or has made a spelling error. The disadvantage of creating a catch-all mailbox is that you may begin receiving a lot of spam, but this problem can be rectified using an anti-spam protection solution. It’s also important to bear in mind that a mailbox with an active catch-all functionality cannot redirect inbound email messages to a third-party mailbox.
