  • WhatsApp forces Pegasus spyware maker to share its secret code
    Just so you know: https://grapheneos.org/ and https://signal.org/ do exist! - Source: Hacker News / 4 months ago
  • What are you shocked people are still doing nowadays?
    Signal works the same but without the user tracking from Meta/Facebook. Many people use it as well but I'm surprised that a majority sticks to WhatsApp. Source: 7 months ago
  • A Practical Guide For Safety And Reporting Crimes For Our Community
    A question I often get is "Well are my text messages safe" The short answer is... Maybe? Depends on what type of phone you use, your carrier, and a bunch of other factors. One way to avoid this is to use an end-to-end encrypted text service like Signal if that is a concern of yours. VERY IMPORTANT NOTES: Telegram and WhatsApp are not secure.

  • Signal Public Username Testing (Staging Environment)
    The linked page is on signalusers.org, but Signal's regular home site is https://signal.org/. I'm looking all over signal.org for some link from there to signalusers.org, as that would make me more relaxed about the authenticity of the latter -- i.e., that it really is run by the same people who run signal.org. Yes, maybe I'm being paranoid. But we're talking about an app whose whole purpose is secure... - Source: Hacker News / 8 months ago

    WhatsApp and Signal: Of course I’m going to conclude with the point to point encrypted communication apps Signal and WhatsApp. Most of our clients around the world communicate in these apps more than they make phone calls or send emails. Set up an account in each app and start leveraging the text, photo, phone and video features to have easy and fast conversations with your global contacts. See https://signal.org...

  • Ask HN: Are you aware of a sane path to selfhosted email server?
    I own domain names, but I'm not smart or techie enough to do it myself. I found Modoboa: https://modoboa.org/en/ and when I finally do it and if they are still around, I'll probably go with them. HTH. - Source: Hacker News / 29 days ago
  • I don't know how I feel about email
    Setting it up from scratch is extremely annoying but there are foss solutions which manages everything mentioned and more, you only need to install & add the specified DNS records. Modoboa does a great job at this: https://modoboa.org/en/ > Also apparently there's no real way to migrate between email servers either This seems false (unless I'm misunderstanding), you can just setup a second mailserver, change DNS... - Source: Hacker News / 12 months ago

    For receiving email, I use Modoboa, but I am planning on moving the backend to Docker Mailserver. I usually reply with a Gmail address though. Until I get the email server configured to send emails through something like Sendgrid. Source: over 1 year ago
