Having set up an email address through Gandi.net (editor@aftertheorange.com, it is now bouncing back emails sent to that address.

I used the Thunderbird feature to create an email account specifically for a project I am working on through Gandi.net. After working successfully for two weeks, messages sent to the address are now bouncing back with a message that the URL (aftertheorange.com) is not found. I have tried sending emails through other accounts, and they have either not arrived or been bounced.
