Cypht - Lightweight open source webmail application written in PHP and JavaScript

@Kubernetes hmm, try some debug set commands https://www.baeldung.com/linux/nginx-log-variable-output

this was interesting too:

or just stick them in a cyclic memory:2m

@girish thanks for pointing me to Apache. I was able to get it running now. Next problem is the authentication.

[girish]

If it has IMAP or SMTP auth, use the "email" addon. Like in roundcube - https://git.cloudron.io/cloudron/roundcube-app/-/blob/master/config.inc.php?ref_type=heads#L9

[Kubernetes]

No luck today, now I just get an error from the App that Invalid auth configuration.

[robi]

@Kubernetes is that a typo in the start.sh?

#sed -i "s/^imap_auth_tls=.*/imap_auth_tls=${CLOUDRON_EMAIL_IMAPS_PORT}/" /app/data/hm3.ini

IMAP vs IMAPS

[Kubernetes]

@robi I think this is okay. In the current state it is not used anyways, because after a change of the .ini a config generation php script needs to be run. So I have to move that to the Docker Image build process, because during runtime it is read-only...

[Kubernetes]

Okay, here we go...

• The Cypht App is using Apache2 to get served.
• The Login (auth) still fails - I have no idea why.
• The PHP Session caching seems to fail in addition.
• The use of redis db doesn't work at the moment.

Some Logs:

The Invalid IMAP auth configuration settings error appeared after I removed the 143 imap port from configuration and kept only 9993 for secure imap

When adding 143 again to the hm3.ini I get this error when trying to login:

Heureka! I got it working now after putting 9993 as "normal/unsecure" imap server port config....
I will prepare the easy installer now and then some more people should check if it works correctly - be carefull and use a dummy mailbox - just in case it starts to run wild and delete emails or so!

During my own tests I found following issues:

• SMTP is not working (outgoing email)
• Profile is not saved - after logout the profile is gone

Excellent, nice work, progress bit by bit!

[SansGuidon]

I'm interested in having this web mail as an alternative to the existing solutions in Cloudron App Store. Any help needed to package it?

[andreasdueren]

@SansGuidon Looks like you can probably install it in a LAMP app

[SansGuidon]

Good to know! I have to investigate then and maybe share the resulting full-install script with Cloudron community once working, as done for yt-dlp (https://gitea.zoemp.be/sansguidon/snippets/src/branch/main/cloudron/awesome-installs/yt-dlp.sh) even if ideally I would like to have it auto updated by Cloudron

[fbartels]

I am currently testing different projects that implement the EWS protocol and came across cypht. I have created a community app to easily install it on cloudron: https://ca.cloudron.io/app/cypht

[jdaviescoates]

Looking forward to giving this a try, thanks for packaging @fbartels !

Great!
From the instructions: „Log in with your full Cloudron email address and your mailbox password.“
Which one is the mailbox password? An app password for mail clients doesn’t work.

[fbartels]

@necrevistonnezr said:

Hmm.. I cannot reproduce this. For me the login works with my users password or an app password with the mail client scope.

[necrevistonnezr]

@fbartels
When setting up the app password, expiry was set to immediately. I can’t explain why…

[fbartels]

@necrevistonnezr ah but that explains why it rejected the password

[jdaviescoates]

Changelog: Enable the fancy login page and allow loading images from external sources by default.

I can't find where the option to enable external sources is enabled.

But I'd also prefer it to be how most clients seem to do it: each message having the option to enable images

[fbartels]

@jdaviescoates This is something you can configure inside /app/data/.env.

Overall, Cypht is definitely built for power users and strictly prioritizes security over out-of-the-box convenience. For example, responses are plain text by default, the timezone defaults to UTC, and settings have to be explicitly saved by re-entering your user password (otherwise they revert on your next login). While they recently launched a very shiny new website, the underlying documentation is still a bit sparse.

Because of this "security first" design, Cypht intentionally blocks all external images by default. To change this behavior so that you at least get prompted to load them per email, you need to toggle the image loading setting.

For context, you can see how this restriction is explicitly handled in the source code here:
cypht-org/cypht - app.php lines 555-570

Keep in mind that the code change linked above only alters the default behavior for fresh installations. If you upgraded from a previous version, your user profile will still carry over the old, stricter setting, so you'll want to manually update it in your configuration.
