Stalwart Mail Server on Cloudron - Secure & Modern All-in-One Mail Server (IMAP, JMAP, POP3, SMTP)

[timka]

I just started using Jmap because of ThunderMail (not Thunderbird), but I really like that server.
@andreasdueren I think having an additional mail server app would be great, but the actual mail server is perfectly integrated into Cloudron itself. Nice find!

If this server becomes more stable (see the breaking changes when updating: https://github.com/stalwartlabs/stalwart/blob/main/UPGRADING/v0_15.md), it could be a very nice drop-in replacement for the internal mail server as long as the licence (https://github.com/stalwartlabs/stalwart?tab=readme-ov-file#license) fits. However, reading the 'Enterprise' options (https://stalw.art/enterprise/), it may not be suitable because 'Multi-Tenant' is an 'Enterprise' feature.

If I find some time, I can do some tests and post the results here, but that's low priority.

I'm experimenting with packaging this. Please help me test it: https://git.due.ren/andreas/stalwart-cloudron/-/raw/main/CloudronVersions.json?ref_type=heads

Hello @andreasdueren, thank you stalwart always interested me but the built-in email in Cloudron is so efficient that I didn't took the time to test it further.

So just to help you and for curiosity I tried to install the software using your json. The install was quick and okay, but I was unable to log in.

Using the redirect to openID with the cloudron admin email adress leads me to this error:

Failed to load the admin panel configuration.
API error 403

So in a new window I've insert the /admin adress and admin as a user and the password stored in /app/data/env in STALWART_RECOVERY_ADMIN=admin:XXXXXXXXXXX

Token exchange failed: 400
Back to login

So I've changed STALWART_RECOVERY_MODE=false to true, restarted the app but got still the same error...

[andreasdueren]

@josephcosta Yes, openID isn't working yet. working on that. But the package should auto create admin credentials you can extract from the env. At least it does for me. Doesn't it have a STALWART_RECOVERY_ADMIN=admin:xxxxxxxxxxxxxxxx entry already?

[josephcosta]

Hello @andreasdueren

Doesn't it have a STALWART_RECOVERY_ADMIN=admin:xxxxxxxxxxxxxxxx entry already?

Yes it does, as I wrote you I tried to access using admin as username and the password after admin: but I had this error:

Token exchange failed: 400
Back to login

[andreasdueren]

@josephcosta Hmm. I'll check it out later today or tomorrow. Thanks for testing!

[andreasdueren]

@josephcosta Please update to 0.16.26, should work now.

[josephcosta]

@andreasdueren I've installed 0.16.28 and accessed succesfully using the credentials stored in /app/data/env, Thanks!

I had to open ports in /home/yellowtent/platformdata/firewall/ports.json and restart the firewall to have access to smtp, imaps, ...

I am not sure if I will proceed further in testing as some interesting features are locked as Enterprise Features...

OK thank you I'll check out the port issue

Any updates on this as a cloudron app? would also be interested

[andreasdueren]

@fanvyr Unfortunately this can't be packaged on an app level

[LoudLemur]

@andreasdueren You are ahead of the game! We were just looking at packaging this and saw you were already testing. Great going, andreas!

[LoudLemur]

@andreasdueren What is the issue with this? Maybe their developers can help us package it.

[andreasdueren]

@LoudLemur The Problem is that the inbound mail port is blocked by cloudron and can not be reassigned without mayor modifications to cloudron. Currently this is a platform limitation and likely will never be supported because it would require the current deeply integrated mail services to be made more modular. I don't think it's something the Cloudron team is interested in.

Right, and to learn more why this is unfeasible look at how DNS MX records work.

They don't have a way to specify a port other than the defaults we all use.
