Have you tried signing up using a webmail service provider? Your mail won't pass through the hands of your ISP, that way.
Off the top of my head, I know of Fastmail.fm, mail.yahoo.com, or even the dreaded Hotmail... Alternatively, if you have your own domain name, like I do, you might be able to use them for your SMTP and POP services.
