What are you doing with the domain?
It looks like you registered it two years ago and haven't done anything with it.
Barring any use of the domain that shows it is clearly NOT intended to infringe on their trademark, I don't think you have much of a case.
I'm at a loss to come up with a concept that does not likely infringe. "Fedex" is a unique enough term that it's not likely you were intending to do something unrelated to shipping. But, I don't want to jump to too many conclusions, so please provide some more background info if you don't mind.
fedexr.com = fede (short for federiko, my nickname in Spanish) + xr (for eXchange rates - I trade currency pairs).
