My main gmail alternative would be going back and have a self-hosted one. For personal mail installing a mail server and if you want a web interface (plenty of good ones) to access it is not hard, and can be made pretty secure. But would miss excellent gmail spam filtering (not hard to add a spam filtering, what is hard is adding one as good as gmail one) and search (didn't tried any self-hosted mail search engine yet to judge). If what worries you about gmail is privacy, then yahoo won't be an alternative. There are a few alternatives suggested in http://prism-break.org http://prism-break.org (including guidelines to install your own one)
