A catch-all mailbox is one that gathers all the emails sent to inactive addresses. For example, if your address is info@domain.com, but somebody miswrites 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 single mailbox per domain name can have this feature activated and in this way you’ll never miss messages because the other side has an out-of-date address or has made a typo. The drawback of having a catch-all mailbox is that you may start receiving lots of unsolicited email messages, but this problem can be fixed using anti-spam protection software. It’s also crucial to bear in mind that a mailbox with an activated catch-all functionality cannot redirect incoming messages to a third-party mailbox.
