A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Thanks for the long answer!

I haven't heard of most of your abbreviations/term till now so I guess this will be one of the bigger journeys through the world of IT :)

I do have to say for the purpose of tinkering I love these bigger projects because you learn so much on the way. Now having read your answer I am even more exited to try it out :D

Oh, my apologies. Here is a definition list :

  • SMTP : Simple Mail Transfer Protocol : the base of any mail system, it's the server you contact to send emails, which relays your mail to an other SMTP server (where your contact is hosted), which stores the mail for user to retrieve
  • IMAP : Internet Message Access Protocol : one of the protocols that can be used to retrieve emails from your mailserver (the other one being POP3)
  • SPF : Sender Policy Framework, a configuration on your domain name specifying which machines are allowed to send mails in its name
  • DKIM : DomainKeys Identified Mail : a signing process (signing each mail) to validate the "From" email address is indeed authorized from the domain it pretends to
  • DMARC : a warning system to let you know when someone pretended to be you (also giving instructions about what to do with emails when SPF and/or DKIM are missing or wrong)
