I've been using disroot.org for a few years and it does what I expect. Recently I started a maddy.email server on a VPS and it's easier than I thought.

doesn’t collect my data and its [sic] secure as well

To quote cock.li,

How can I trust you?

You can't. Cock.li doesn't parse your E-mail to provide you with targeted ads, nor does cock.li read E-mail contents unless it's for a legal court order. However, it is 100% possible for me to read E-mail, and IMAP/SMTP doesn't provide user-side/client-side encryption, so you're just going to have to take my word for it. Any encryption implementation would still technically allow me to read E-mail, too. This was true for Lavabit as well -- while your E-mail was stored encrypted (only if you were a paid member, which most people forget), E-mail could still technically be intercepted while being received / sent (SMTP), or while being read by your mail client (IMAP). For privacy, we recommend encrypting your E-mails using PGP using a mail client add-on like Enigmail, or downloading your mail locally with POP and regularly deleting your mail from our server.
