The most important factor with email, is that your inbox is encrypted at rest at all times... and cannot be bruteforced. The chances of your email messages being 'man in the middled' are almost non-existent. Its a micro-percent of live investigations that does this. The police RELY ON finding messages in either your inbox or the recipients. It doesnt matter if they are encrypted or not in reality. Of course they'd li…

You have? Why?

Earlier quoted context omitted.

Only because we choose it to be. When you use XMPP or Matrix you know your message will be delivered instantly. When you use email you don't. But that's only because we haven't defined an extension that tells the client whether the server can deliver messages instantly. It's not really that inherent to the system. Surely you've had at least one real-time conversation by email because both of you happened to be online…

Yes, it's theoretically possible to adapt many protocols to many use cases, but that doesn't mean it's a good idea. Email and XMPP are just geared towards very different use cases. In particular, Email has a lot of assumptions about acceptable delivery delays, bidirectional (non-)reachability etc. baked in that would be very hard to globally undo.

As programmers, is it not our natural instinct to create a ChatSystem and MailSystem on top of a GenericMessageDeliverySystem? When did we stop doing that? Creating a brand new GenericMessageDeliverySystem for each purpose comes with substantial costs. We don't reinvent the Internet to create WhatsApp.

In a sensible world, we would be using this, instead of whatsapp. It is amazing that even really a vast majority of, even technical people, not once stopped and looked at whatsapp, and said "Wait, e-mail can do this, we just need a pretty UI".

> "Wait, e-mail can do this, we just need a pretty UI" This reminds me on this nice comment thread: https://news.ycombinator.com/item?id=19217818

i have been arguing this ever since ICQ became popular. back then i got a lot of angry reactions. i already explained it here: https://news.ycombinator.com/item?id=38029579

that generic server backend that i am describing in my linked comment is something i am using here: https://news.ycombinator.com/item?id=42159045

I wish I could send a one-time link to my father where we could play chess against each other by re-visiting the same link. The e-mail part made me think of this. I have no use for an e-mail based chat but an online chess game that's easy to use without registration would be cool. He's 82 and he can't use complex sites.

well then deltachat is exactly what you want because it supports webxdc apps which can run in the deltachat client. here is the chess app: https://webxdc.org/apps/#arcanecircle-chess

No, if anything we'd be using XMPP or Matrix. Email is the completely wrong protocol choice for instant messaging. It's just a completely different use case. You wouldn't send a letter to the fire department if your house is on fire either.

I think the point is that it builds on existing infrastructure that almost everyone already has in their life. Whether you self-host, use a niche provider, or a mainstream provider, email provides a pretty interoperable starting point which isn't a walled garden and doesn't have to be owned by FAANG.

Are there some compromises? Of course. But creating new accounts, or using new services isn't one of them. Email-speed instant messaging is good enough for me.

And to be honest, as much as I like Matrix, it has plenty of compromise of its own - including speed/reliability when using their own servers.

would be nice if all the "no, no, this can't work! email is slow! blah blah" guys once and for all actually give it a try to the app and realize IT WORKS AND IT IS BLAZING FAST! I have been using it since years with my family and some friends without any problems, it is the best I could find after trying Matrix, XMPP, etc.

What generic message delivery system are you talking about, though?

SMTP is optimized for the use case of email; XMPP is optimized for one-to-one instant messaging; Matrix is optimized for "Slack-like" chat.

I highly doubt that these three use cases are similar enough to warrant introducing an additional common protocol/layer.

Several years ago I tried DeltaChat and it caused an insurmountable problem: my mail provider kept locking me out of my account. Almost certainly it was because DeltaChat's suspiciously ciphertext-filled messages were triggering the abuse lockdown. The provider was GMX and it was their fault, not DeltaChat's. But I had to call off the experiment.

> The provider was GMX and it was their fault, not DeltaChat's.

Noting that the team have put together "Chatmail" a minimal email suite designed for speed, security and convenience.

Also helps with the whole "onboarding to chat" and multiple identities not linked to existing accounts.

There are multiple public servers which may be an option, instead of using an existing email account at provider X.

My first question on this sort of thing was how well does it work with GMail. And they have an FAQ entry on it: https://providers.delta.chat/gmail

The whole purpose of using a distributed IM like Delta Chat is to break free from big data leeches like Google. If you're just using Delta Chat with a centralized Gmail server as the backend, doesn’t that defeat the point?

at one point that used to be how email worked too. for me the point of using deltachat is that it works with my existing service and that it does not depend on any particular company/service. issues with google are secondary. deltachat is still useful even with gmail.
