If you are willing to pay, a lot of ISP's will offer you an email only account for pretty cheap. I have one with core.com. I pay 50 bucks a year, so less then ten bucks a month. For this I get email and a few MB of webspace. I can use any third party email software that I am aware of. There is also a web email interface. It has pretty good spam controls. Not much gets through that I don't want. Although, to be honest I have never used it for my PBW emails so I don't know for sure it won't block those.
