There are plenty of domain name scams out there, I have spoken about SEDO branded ones, Chinese domain name scams and there are plenty of others.
They are all generally trying to trick you into either registering a name similar to the one you own or trying to encourage you to renew with them as opposed to your current provider.
What is common among most is that the prices they charge a far higher that they should be.
One that did the was the Domain Registry of America (wiki entry), they would send out renewal notices in the mail, hoping for someone to fill it out and send it back hoping they didnt realise that it was not from their provider or that the charges were much higher than normal.
Anyway, I got a similar email, today. The key things here is that it is for a legitimate domain, but the registration is for USD79.95 per year, far more than you can register or renew a domain.
With most scams, they use language to lure people into thinking they are legitimate, in this case talking about ISP (Internet Service Provider)
Now this service is not necessarily illegal, because anyone can renew any domain name, however, the issue here is the price.
Here is the transcript of the email.
