Hushmail Business customers can setup a catch all account that receives all email sent to any address on their domain that does not have a specific email account setup. Customers can use catch all accounts to ensure all email sent to your domain gets delivered, and save money by having less accounts on your domain. This feature is available as part of the domain administration service option for Hushmail Business.
To enable Domain Administration please see the Making changes to your Hushmail Business services article.
Alternately, if you contact us we can add a catch all address for you at no extra cost.
