I often use Tor, not because I'm doing anything illegal I just don't want the NSA/CIA/FBI/etc spying on me. The one thing I've never found a replacement for is an email account. Most providers, such as gmail and outlook, will block any attempt to signup using Tor and then they ask for personal identifying information anyway, once signed up.
Are there any email service providers that are Tor friendly? I've tried a couple disposable email accounts but most of those delete emails after one hour so they are not ideal.
