I find it really amuzing that IT-departments around the world is just plainly copying the example DNS-records in my blog-posts about DMARC.

Resulting in me getting reports about their domain to my inbox

I'm pondering on, instead of self-hosting, buying some #email service.
I need:
- Multiple separate inboxes (NOT aliases!)
- #IMAP / #SMTP, the whole alphabet, I want to use #Thunderbird.
- Not "one of the big guys" like Google/Microsoft/Yahoo/WhatHaveYou
- Protonmail is... Not sure, but their "email addresses" === aliases
- I'm going to have to stick with #SelfHosted am I not?

@protonprivacy We're also #hiring #juniors: https://grnh.se/tfdgi4f2teu, this time in #Skopje, #Barcelona, and #Prague.

This is for the #ProtonMail Inbox team (an umbrella for Mail and #ProtonCalendar where I sit). The Desktop team covers things like #MailBridge, a tool that allows you to setup a local #SMTP and #IMAP server which will transparently decrypt your emails *locally* and let you connect a regular #email client like #Thunderbird or #Outlook. This is #OpenSource: https://github.com/ProtonMail/proton-bridge!

Not everyone can or should self-host, but there is a lot of middle ground between self-hosting and putting everything on #AWS.

Federated protocols like #XMPP, #ActivityPub, and #SMTP give you choice.

Question technique.

Je voudrais monter un "petit" service d'emails de type RSS to Newsletter.
En gros pour offrir depuis un service de newsletter sur un site depuis son flux #Rss

Je ne trouve pas de service simple proposant cela et surtout très RGPD compliant et situé en France/Europe.
Le point qui me bloque c'est de trouver le service de Smtp-relay par lequel passer.
Vous auriez des idées/recommandations ?

Ou plus simplement un tel service vous intéresserait ?

#email #newsletter #smtp

Are there any reliable and trusted "self-hosted" options for email? Ie. you get a private VPS with your own SMTP-server running.

Basically all that would be required to run your own "email" server. But not be part of a shared hosting setup.

In 2013 I wrote up "Maintaining A Publicly Available Blacklist - Mechanisms And Principles" (also https://bsdly.blogspot.com/2013/04/maintaining-publicly-available.html) . TL;DR: blocklisting is a kind of public shaming, be sure your process is verifiable and transparent.
