If I want to send emails to friends who use Google, Yahoo, AOL, etc., how can I currently use my local email client to send a metadata-free* email to them?
E.g., is it possible to bypass my own mail provider and directly contact my friend's mail server with an encrypted mail with only one identifying header, TO: email@example.com? Upon decryption, they realize it's FROM: firstname.lastname@example.org, sent at TIME, with SUBJECT: subject.
*Metadata-free means the only devices that know SENDER (IP address, username, etc.) contacted RECIPIENT are devices that belong to SENDER or RECIPIENT. An anonymous email account does not pass this test and is thus vulnerable to analysis of its email contacts and traffic.
- Would self-hosted mail servers help in any way?
- Is SMTP the bad guy making this idea impossible?
- Are mail providers the bad guys?
All help appreciated!
