A catch-all e-mailbox is one that gathers all the email messages sent to nonexistent addresses. For example, if your email address is email@example.com, but someone misspells it and sends an email to firstname.lastname@example.org, it will still be received in the catch-all mailbox that you have set up. Only one mailbox per domain name can have this feature activated and thus you’ll never miss messages because the other side has an out-of-date email address or has made a typo. The drawback of configuring a catch-all mailbox is that you may begin receiving lots of unsolicited bulk emails, but this problem can be solved using anti-spam filtering software. It’s also essential to know that a mailbox with an activated catch-all feature cannot forward incoming email messages to a third-party email address.
