A catch-all e-mailbox is one that captures all the messages sent to inactive addresses. For instance, if your email address is info@domain.com, but someone mistypes it and sends an email to inof@domain.com, it will still be received in the catch-all mailbox that you have set up. Only one single mailbox per domain name can have this feature activated and thus you’ll never miss emails because the other side has an outdated email address or has made a mistake. The drawback of having a catch-all mailbox is that you may begin receiving a lot of junk emails, but this issue can be fixed by using anti-spam filtering software. It is also important to bear in mind that a mailbox with an active catch-all functionality cannot redirect inbound emails to a third-party email address.
