No idea I'm afraid then - I thought every major webmail service could do forwarding. You can't even use the free hotmail accounts with Mail or Thunderbird or any other Mail client not made by MS.
I like Gmail too but the OP asked for hotmail forwarding. try checking out gmx.com. Someone posted earlier, saying that this site can grab email from hotmail, gmail, yahoo, and put them into their domain. you could try that.
