A catch-all e-mailbox is one that collects all the email messages sent to invalid addresses. For instance, if your address is info@domain.com, but someone misspells it and sends an email to inof@domain.com, it will still be received in the catch-all mailbox that you have configured. Just one mailbox per domain name can have this feature enabled and thus you will never miss emails because the other side has an outdated address or has made a typo. The disadvantage of creating a catch-all mailbox is that you may begin receiving plenty of unsolicited email messages, but this problem can be resolved using an anti-spam filtering solution. It’s also important to remember that a mailbox with an enabled catch-all functionality cannot forward incoming messages to a third-party address.
