A catch-all e-mailbox is one that collects all the email messages sent to inactive email addresses. For instance, if your email address is firstname.lastname@example.org, but somebody misspells it and sends a message to email@example.com, it will still be received in the catch-all mailbox that you have set up. Only one mailbox per domain can have this feature enabled and in this way you’ll never miss emails because the other party has an out-of-date email address or has made a spelling error. The negative aspect of creating a catch-all mailbox is that you may start receiving lots of spam messages, but this problem can be resolved using anti-spam protection software. It’s also vital to remember that a mailbox with an activated catch-all feature cannot redirect inbound messages to a third-party email address.
