What's coming in Cloudron 10

[mononym]

As this is about email, I wonder if there's a way to have a chatmail relay. Kind of "batteries included" for the couldron email addresses or so. But I guess that's out of scope. Just came across that project again because it got some larger grant: https://www.sovereign.tech/tech/chatmail

Hello @mononym
From just a quick read of the description of the repository I would lean towards no.
Cloudron uses haraka as the underlying Mailserver which we also contribute to regularly and Chatmail is a full Mailserver which would be conflicting.

@james @mononym unless chatmail can delegate and use Haraka instead?

[sponch]

would it -theoretically- be possible to and an alias service (like simplelogin.io or addy.io)?

[andreasdueren]

@sponch I don't think so. Looks like cloudron is blocking Port 25 which is needed for receiving mail. Running into the same issues with my attempt at packaging stalwart

[joseph]

For external software (unsupported), you have to explicitly unblock ports - https://docs.cloudron.io/network/#whitelist-ports

[andreasdueren]

@Joseph No, the problem here is that to receive mail, I need to be able to route Port 25 to the app. But I think it's always reserved by the internal mail server?

[joseph]

@andreasdueren you are right, it is a reserved port .

The ability to delegate a subdomain out to an SMTP server hosted by an app has been discussed several times before. I'd quite like to package Mailman for Cloudron, but need a way of getting mail into Mailman itself. Mailman processes incoming mail via LMTP, but we could run an MTA on the app container if the app didn't support native SMTP. If we went that route I think it would be essential for Haraka to call forward to the SMTP server running in the container to avoid backscatter. I do run Mailman on my Cloudron instance for now in a completely unsupported manor and allow incoming SMTP via the Cloudron firewall as a custom port. This is working fine with Exim installed natively on the host, and I have a script to ensure the Nginx config for Mailman is in place. I really wouldn't recommend doing this yourself though and I'm also thinking of offloading the mailing lists to a third party provider at this point for various reasons.

Ubuntu 26.04 support

This is now implemented in master. Required very minimal changes, mostly to the installation script and also fixing up the docker version.

Ubuntu 26.04 is slowly appearing in many VPS providers (linode, vultr, upcloud) but not in DigitalOcean yet. So, haven't tested it extensively.
