Catch-all email addresses receive any mail to your domain, that isn't addressed to a mailbox. Some people find them very useful, but they can tend to attract spam. To add a catch-all mailbox to your account, log-in to the control panel (http://control.status-guru-host.com) and select the website/domain name that you'd like to add a catch-all mailbox for.
Click the "Email" icon, and then click the icon to create a forwarder.
The forwarder should be *@yourdomain.co.uk (asterisk, which represents a wildcard at your domain) > anothermailbox@yourdomain.co.uk
This will make anothermailbox@yourdomain.co.uk become a catch-all account, and it will receive any mail to your domain name that doesn't have a mailbox setup.
