More and more I am looking through @Delta Chat apps and resources I believe this should become number one messenger of choice for screen reader users.
The developers are constantly improving its #a11y. It's secure from the start of using.
Additionally the desktop chat has under gone an #accessibility audit and accessibility issues are clearly documented in public.
I am not sure other messenger style app on the planet has such dedicated commitment to accessibility ever.

Issues from Accessibility audit · Issue #4743 · deltachat/deltachat-desktop

We recently got an accessibility quick scan from HAN. They took some time to discuss/test the app with us in a call and gave us a report. treefit and wofwca also made notes during the call, this is...

I am happy to hear this, just trying to come up with a way to host an email server via my home internet. Dynamic IP (should not be an issue), ISP blocking SMTP ports (25 and possibly others) which is where I'm stuck.

Is there a way we could test that? Before we decide to use it or so. I don't know how it works, so I'd like to test it. Call me an experimentalist, or something. ;)

@Winter blue tardis🇧🇬🇭🇺 Yes, let's try it out if you like. I know you are on IOS, so look for deltachat in the app store. Minimum requirements: iOS 14, iPhone 6s, iPad 5/Air 2/Mini 4.

I also have an Android, Mac, Windows, and if I make linux work, I will have too many things and it'd be fun to try it on. Should be a fun little experiment. I sent you a dm, and asked you a few things so we don't spam. LOL

@Erion Yes, SMTP port 25 for server to server communication is a protocol requirement that is not possible to substitute I am afraid. In the readme of the @Delta Chat #chatmail relay they are recommending to use a cheap VPS to host the whole thing or route the public IP address to your home using VPN.

it's correct that the current chatmail relays require port 25 to be reachable. There are some discussions around other server-to-server transports, reflected in github.com/chatmail/relay/issu… even if mostly talks about Tor. The email system is traditionally pretty flexible about transports, especially server-to-server ones. There are also some deployments that use uucp for long range radio based transporting between MTAs.

Internet Mail 2000 · Issue #487 · chatmail/relay

We want to be able to accept mails from .onion domain. We cannot have DKIM authentication as there is no support for DNS (see https://forum.torproject.org/t/mock-dns-records-for-onion-services/4671...

I haven't tried it yet, but initial docs' reading at its web site suggest it is fantastic indeed.

@clv0 My biggest problem adopting this is, I can't find a reliable, IMAp-compatible mail provider who wouldn't ban me after five minutes for trying, in their eyes, fishy apps. Any tips?

@clv0 Yes, it works great for chatting between Delta users. I was hoping, however, that I might be able to chat with my regular e-mail contacts, using Delta as a more convenient interface to achieve that while they use whatever they usually do to access their emails. I believe the default server requires authentication on both sides so Delta needs to be used on both ends.

@Piciok @clv0 ah, using delta for cleartext mail requires a classic email provider indeed. It's best to use a separate profile for that, and not mix it with e2ee encrypted chatting.

@clv0 Which is where my problem kicks in. I was the most successful with Onet, one of the biggest and best known Polish providers, however they banned my newly created account instantly after noticing I was chatting from Delta, no doubt sensing suspicious activity.

@Paweł Masarczyk While testing I have used gmail or my own classic email account. It worked but I have understood using #chatmail servers is what makes it most attractive. I think I have read a blogpost from someone a few months ago explaining this very well that inspired me, however I can't find that article in my browser history right now. CC @Cleverson @Delta Chat

@clv0 @Piciok posteo should be fine. They have rate limits but unless you are entering very large chatty groups that shouldn't matter.

@Paweł Masarczyk @Cleverson I know you are looking for a way to stay in contact with people you are already connected to using traditional email. Still I would recommend creating a #chatmail account on your relay of choice just for testing so you can start with an empty profile and you'll get to experience the @Delta Chat the way it has been meant to. Then as an exercise continue with other more advanced scenarios such as classic email login.
The #chatmail based onboarding is really very simple, there is nothing to do wrong.

@patricus @clv0 @Piciok you will need to share an invite link because the email address it not enough to establish end-to-end encrypted communication. You can get the invite link behind the QR code button. Moreover, we suggest to send such an invite link privately, to prevent abuse by anyone joining a chat ;)

@patricus @clv0 @Piciok you can post the invite link publically but some of the MITM-protection guarantees that invitelinks provide degrade then. In this case, somewhere deep in a Fediverse thread limiting visibility of the post to "mentioned users only" would do it.
