A catch-all e-mailbox is one that gathers all the email messages sent to inactive addresses. For instance, if your address is firstname.lastname@example.org, but someone 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. Just one mailbox per domain name can have this feature activated and in this way you’ll never miss emails because the other party has an obsolete email address or has made a spelling error. The disadvantage of configuring a catch-all mailbox is that you may start receiving plenty of junk messages, but this problem can be resolved using anti-spam filtering software. It’s also crucial to remember that a mailbox with an active catch-all functionality cannot forward incoming messages to a 3rd-party email address.
