Longish read , that is well argued...

The Purpose of Protocols

Every open social protocol generates shared resources, but none has produced a governance framework adequate to those resources. So who fills that vacuum?

@hcf that's just wrong and you know that.

For example, if "#Security" was a real issue, they'd host their #IMAP+#SMTP access exclusively over @torproject / #Tor because #OnionServices are using fully-encrypted connections in a self-authenticating adress spaces.

  • They don't because that isn't the issue, and I'm not talking about the Server-to-Server - Connectivity, which is INHERENTLY AND UNFIXABLE INSECURE WITH EVERY EMAIL PROVIDER unless they don't allow actual cross-provider eMails (or restrict it to very few, selected competitiors with spechally negotiated connectivity [i.e. #VPN|s], which to my knowledge NONE of the commercial providers do)…

I brought up @monocles because they at least don't lie to customers and are honest about security & privacy!

@hcf @dans_root @earthnewstech except both fuck up their self-hosted PGP which doesn't doesn't do real #E2EE if you don't exercise #SelfCustody of all the keys and use #PGP/MIME over #IMAP+#SMTP!

I'm sure there are some caveats about interpreting the pretty picture and data this way, but a neat visualization just the same.

To be perfectly honest, #Mailcow continues to impress me. There are countless options for fine-tuning; but once installed and the basic settings configured, it does exactly what it's supposed to. Everything else is just a bonus.

#SMTP, #IMAP, #POP, spam filter, #DKIM signature, webmail with S/MIME capability, #CalDAV, #CardDAV, #SIEVE

I finally managed to configure Postfix correctly as my SMTP on my home server. Now I can use it to send email notifications for Nextcloud, Watchtower and Uptime Kuma (and can ditch Discord for that purpose)
