  • SMTP is only encrypted if the second server responds correctly to the first servers starttls.

    The striptls type of attack, which prevents the servers from getting a valid starttls exchange, was in use over a decade ago by some telcom against its own customers.

    Even if you know the person you’re emailing has a correctly configured client you can’t control a man in the middle attack between servers which has been in widespread use for years.











  • Set an iCloud recovery passcode. It removes the ability to recover your iCloud account by verifying that you’re the owner but it also removes the ability of Apple to be compelled to access it.

    Op: read about pgp/gpg. Do it now. When you don’t understand something ask questions about it instead of giving up.

    Email was never intended to be private. It was never designed with privacy in mind and your use of a client employing an encrypted connection to your mail server does not solve the problem because tens of thousands of mail servers use unencrypted connections.

    No one needs your iCloud to read your email, they can just look at the plaintext mail coming to and from the server.



  • It’s not p2p but at least many years ago:

    SMS.

    If the Internet outage is local then the towers would still work and you’d be able to get texts. I went through a few storms where wired home internet was down, the towers weren’t giving me a data connection (no mobile web browsing or anything), but I was able to send and receive texts.

    If you really care about what you’re asking after, do what someone else said and get a radio license. It’s 150 year old technology and every time something happens radio operators pop up some kind of emergency communications or bridge to the internet through repeaters or something.
