Changing the delta chat agent to another one

Feature Proposal
1

Hi all, after reading this topic, I thought it would be nice to be able to change the delta chat agent to another one, for example, create a list mail.ru, yandex.ru(yandex mail), etc. So in settings delta chat we can choose the agent ourselves and thus bypass the blocking of whitelists if the application is defined as delta chat and not mail.ru for example.
Is it possible to implement this?

Is there a working way to bypass Internet blocking in Russia using white lists?
Perhaps we should start by solving this issue?

There is, and spoofing the agent would be very helpful

4

if there is, then tell us about it, if it is really working and stable, then why not use it?

These are still our own actions (being tested). They are not ready for public discussion, but they are there.

Pinging @WofWca.

This sounds like a good feature request. Can we tag this thread as a “Feature request”?

I am not sure if I am completely understanding the situation and the suggestion. If Delta Chat works with mail.ru and yandex.ru email accounts, given that you have followed the steps in https://support.delta.chat/t/update-documenation-for-using-mail-ru/4421?u=wofwca, then the feature discussed here (“agent spoofing” / “mimicry”) would be pointless, because everything is already working as well as it can.

I suspect that original post implies that if you just mimic the traffic pattern, then you’ll be able to connect to any mail server in the world and not just the whitelisted ones. I am pretty sure that the only way to do this (given that this has not been patched by the censors yet) is to manipulate TLS SNI, replacing it with yandex.ru / mail.ru, as described in posts around https://ntc.party/t/обход-белых-списков-теория/19123/24.
I personally am not aware of whether this has ever been utilized for IMAP / SMTP and whether this is possible.
For reference, Delta Chat and SNI have been discussed here:

If it is possible, I personally doubt that Delta Chat devs are gonna spend resources on this, given how easy it is, in my understanding, for censors to patch this SNI loophole.

In short, I suggest to simply use the “third-party email client setup” approach (described in https://support.delta.chat/t/update-documenation-for-using-mail-ru/4421?u=wofwca and https://providers.delta.chat/yandex-ru), which will let you use Delta Chat and connect with people inside and outside of the country, as long as mail.ru and yandex.ru do deliver your emails to their destinations (so far I am only aware of mail.ru not working with protonmail.com).

It definitely makes sense, even if all the SMTP and other stuff is Mail or Yandex, the Delta app should still pretend to be Mail or Yandex. This is my opinion

Uh, @bestman, did you accidentally tag my post as a solution? It was just a ping and a nitpick. :slightly_smiling_face:
