I got a very official email full of legalese the other day stating it was a final notice that my domain name was going to expire. It appeared that it was from my hosting company.
Now I consider all emails not from friends to be questionable. So I checked my domain information first and saw that it did not expire for some time. Next I did a Google search on the email and found it was a common scam. Basically another company trying to trick you into switching your domain to them. I notified my hosting company of the email and reported it to the
FTC.
