A catch-all email mailbox is one that collects all the email messages sent to nonexistent addresses. For instance, if your email 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. Only one mailbox per domain can have this feature enabled and in this way you will never miss emails because the other party has an outdated email address or has made a spelling error. The negative aspect of setting up a catch-all mailbox is that you may start receiving plenty of unsolicited emails, but this problem can be rectified by using anti-spam filtering software. It is also crucial to know that a mailbox with an active catch-all feature cannot forward incoming emails to a third-party mailbox.
