A catch-all e-mailbox is one that collects all the messages sent to non-existent addresses. For instance, if your email address is info@domain.com, but someone misspells it and sends a message to inof@domain.com, it will still be received in the catch-all mailbox that you have created. Only one mailbox per domain name can have this feature enabled and in this way you’ll never miss emails because the other party has an obsolete email address or has made a mistake. The downside of creating a catch-all mailbox is that you may begin receiving lots of spam emails, but this problem can be rectified using anti-spam filtering software. It is also crucial to keep in mind that a mailbox with an activated catch-all functionality cannot forward inbound messages to a third-party mailbox.
