Heaps of them...
It depends what you want and what you're prepared to put up with.
E.g: Mail.com will let you choose from a variety of domain names - I have one from them which is
delboy@musician.org but it also has annoying popups when you log in and even worse - every time you delete an email!
Other ones I know of are Netscape, 37.com, Lycos, etc
In fact, have a look
here - there are hundereds - some good, some bad. You can always try a few before giving out your address and see which one you like. Just cancel or forget about the other ones - they get deleted eventually.
