With the recent-ish cock.li situation along with previous events surrounding it and Fedora Mail, I don't think I can trust email services run by a single guy anymore, especially if they target the imageboard crowd and/or use meme domains.
I think I'm going to use Posteo for now on. They same to go out of their way to respect user-privacy despite being for-profit and being payed means that it is less likely to be used for some bomb-threat or something like that (hopefully).
@vokainen099 Fedora Mail had it's registrations permanently closed for over a year now because someone made a throw away account to send a bomb threat. I think @j could open an account if you ask him though.
But they recently may have reopened, it seems it was green again, although I didn't bother to check, don't need it for now
