OX COI Messenger - a Flutter app for the COI (Chat Over IMAP) standard

Last update: Dec 23, 2022

Overview

Project on hold for now

Please note that the OX COI Messenger project is currently not active. In the past this project was hindered by the lack of Rust expertise on side of the project maintainers. Work is underway to create a new approach which also allows users to manage normal email messages. If and when we have something to announce, we will update this section. For now, we keep this reference for interested developers.

3 Dots behind every message sendet from OX-Coi to Delta Chat
Describe the bug If I send a message from the OX-Coi Android App to the Delta Chat Android- and Desktop Client I have behind every message 3 Dots [...]

See also the attached screenshots

To Reproduce Occurrence: always Steps to reproduce the behavior:

Send a message via OX-Coi Android App and receive this message via Delta Chat client

See what I described

App information (please complete the following information):

App version: OX-Coi V. beta-2 (2002) Delta Chat V.0.510.1

Delta Chat Core version: I don't know

Flutter version: I dont know

Smartphone (please complete the following information):

Device: Huawei nova

OS: Android 7.0

Additional context I have no idea is this a OX issue or a Delta Chat issue.

But I'm sure the OX team and the Delta Chat team have to work together and have to keep there clients 100% compatible. Only if the good boys work together there is a chance against the big players.

I think with Chat over E-mail there is a realistic chance to replace WhatsApp with E-mail ;-)

I also opened a issue for Delta Chat: https://github.com/deltachat/deltachat-android/issues/1082

Difference to Delta Chat

Hi, what is the difference to Delta Chat https://github.com/deltachat/deltachat-android/? DC seems to be further "developed" (already is on the Play Store and F-Droid) but has not such a nice icon :wink:

Obviously, for the final product it might be the best to merge DC and ox-talk but this doesn't work very often :disappointed:
question

Support proper threading for non-coi users

Is your feature request related to a problem? Please describe.

My current test setup is a custom mail server. On my android phone I have your app and DeltaChat installed (with the same server connection). For testing I sent messages to a microsoft exchange server, read mails there via outlook.

Outlook supports a threaded view of mails, which is very helpful when following conversations. I see this as a very important feature for chats. Of course it's a client side feature, but incoming messages to non-coi users are not put in the same thread.

I receive the message from the app and can answer it. When sending another message, outlook displays it as a new mail, starting a completely new thread.

I should note that messages from DeltaChat arrive in the same thread I started before. So there is a possibility to support this.

Describe the solution you'd like

E-mails should be placed in the same thread.

Describe alternatives you've considered

I don't see alternatives.

Additional context

Compare with DeltaChat. It works there. Maybe it's some header field or some envelope thing.

Show spam folder
Is your feature request related to a problem? Please describe. I set up a test account from @web.de, a popular email provider, but none of the incoming messages showed. The app showed a warning about spam filters, so I removed the spam filter in the email application, but I dont think this can be expected from every user and I imagine many would quickly be frustrated and leave.

Describe the solution you'd like I suggest to include messages from the spam folder as well – maybe as some kind of subfolder in the Chats activity. Visible only if relevant messages appear inside. This way the user will never wonder where their messages went.

Describe alternatives you've considered

Spam folder messages could also be completely hidden by default and shown as an opt-in. Better than now, but imo not a preferable solution due to the reasons outlined above.

Additional context Additionally, it would be great if you could opt in to treat spam messages like normal messsages and simply blend them in, ignoring the mail server's spam detection mechanisms. The less hassle for the user, the better, right?

Internal Bug Tracker.

Besides, a more generic question: Is OX COI supposed to also be a viable replacement for conventional email clients?

If yes, are there any plans to also fetch past messages when setting up an account? Will we ever see folders in ox-coi? What about imap search functionality? Just curious as I couldnt find a roadmap.

If not, should everyone really keep both an email and a coi client on their devices? Would not seem right.

Sorry for all the issues, but I hope they help. I hope I'll find time in future to also contribute to the project as it looks really promising. coi coi coi :+1:

"Login failed" without any further information
Describe the bug When I log in with my custom mail server configuration, very similar to #162 (same ports), the only error message I see is "Login failed". It should work however, my provided login information is definitely correct. But the more immediate problem here is that there doesnt seem to be a way to see the cause of the failure (see screenshot below)

To Reproduce Occurrence: always Steps to reproduce the behavior: This will be somewhat verbose as the behavior varies from case to case. The main issue is with point 1:

Normal login with custom information:

Configure mail settings: Manual settings

Custom mail server from https://lima-city.de. See screenshot below for connection details

Insert correct credentials and mail address, click "Sign in"

Expected behavior: successful login

Acutal behavior: Loading progress continues until 86.0%, then error "Login failed" without details

Same with detailed information:

Insert complete detailed information, including ports

Expected / actual behavior: same as 1.

Endless loading screen with invalid password:

Insert wrong password, then sign in

Expected behavior: Error: Invalid credentials

Actual behavior: Loading progress continues until 65.0%, then stops and loads forever, not even an error message. Need to kill the app.

Without specifying mail server addresses (they do not match the email address domain name):

Remove mail server entries

Expected behavior: Error: Could not connect to server

Actual behavior: Loading progress continues until 80.0%, then error "Login failed" without details

With IMAP TLS port:

Insert correct mail servers and password like step 1

Set IMAP port to 143, leave IMAP Security at "Automatic", then sign in

Expected behavior: Same as 1, as lima-city seems to accept port 143 via TLS

Actual behavior: Loading progress continues until 86.0%, then error "Login failed" with detailed message (yey!) Could not connect to mail.lima-city.de:143: async_native_tls: error:1408F10B:SSL routines:ssl3_get_record:wrong version number:ssl/record/ssl3_record.c:332:

Screenshots Login error:

lima-city.de login information:

App information (please complete the following information):

App version: v0.600.3.1006 – according to Aurora Store, from where I installed it

Plugin version, Delta Chat Core version, Flutter version: I'm sorry, but I cannot see any way to determine those version numbers.

Smartphone (please complete the following information):

Device: Samsung Galaxy S4 Mini, see LineageOS Wiki

OS: MicroG+LineageOS 14.1 (Android 7.1.2)

Additional context Interestingly, I faced very similar issues with Delta Chat: I could not connect with the lima-city mail server either. In that case, I got the error message that the SMTP connection to port 25 was rejected – even when I typed in SSL/465 which sounds very much like #162 too. But that issue was fixed, it seems. And this isnt Delta Chat, so probably not related.
