A catch-all e-mailbox is one that gathers all the messages sent to nonexistent email addresses. For instance, if your email address is firstname.lastname@example.org, but somebody misspells it and sends an email to email@example.com, it will still be received in the catch-all mailbox that you have created. Just 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domain name can have this feature activated and in this way you’ll never miss messages because the other side has an out-of-date address or has made a typo.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 disadvantage of setting up a catch-all mailbox is that you may begin receiving a lot of junk email messages, but this issue can be solved using anti-spam protection software. It is also vital to know that a mailbox with an activated catch-all feature cannot forward inbound emails to a third-party email address.
