I just tried to email email@example.com, and I got this message: Hi. This is the qmail-send program at mail01.internetmailserver.net. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. <firstname.lastname@example.org>: 220.127.116.11 does not like recipient.

I tried email@example.com too, and got the same message. I hope they haven't just grabbed my money and run!
