The purpose of a catch-all email account is to allow you to receive mail that is sent to your domain, but sent to an email address which does not yet have a POP3 email account.
Your catch-all email account will 'catch' this email for you and forward it to a specified email address.
This demonstration shows how to create a catch-all email account.
Select the domain from the drop down box you wish to setup the catch-all for.
Enter the email address you wish your email to be forwarded to (the email address does not need to be hosted with us) or enter ":fail: no such address here", if you wish to stop receiving all unrouted email.
