A catch-all e-mailbox is one that gathers all the emails sent to inactive email addresses. For instance, if your address is info@domain.com, but somebody misspells it and sends an email message to inof@domain.com, it will still be received in the catch-all mailbox that you have configured. Just one mailbox per domain can have this feature enabled and thus you’ll never miss messages because the other side has an outdated email address or has made a spelling error. The disadvantage of having a catch-all mailbox is that you may begin receiving plenty of unsolicited bulk email messages, but this issue can be rectified using an anti-spam protection solution. It is also vital to remember that a mailbox with an active catch-all feature cannot forward inbound email messages to a third-party mailbox.
