How to create Sender from outbound mail ?

[mononym]

Hello.

I think setting up Keila is straight forward, but I can't figure out how to add the outbound mail as Sender. The main question is: can I simply use the outbound email provided by Cloudron fot the app or do I need to set up a Cloudron mailbox for the app ?

In the Cloudron app dashboard of Keila, the email tab shows an outbound email. I set it to keila@domain.net and save. In Keila, I need to set up a Sender: https://www.keila.io/docs/senders. I attempted to follow the answer here: https://forum.cloudron.io/topic/3247/need-help-with-the-smtp-settings/3?_=1771073978666

Server = my.domain.net
Username = keila@domain.net
Password = my domain cloudron password
Connection security = STARTTLS
Port = 587

The above settings fail to send the email:

Feb 14 14:19:28 2026-02-14T13:19:28.248 [warning] Failed sending email to valid_email@mailbox.org for campaign nmc_xogqjL2z: {:no_more_hosts, {:permanent_failure, ~c"109.77.148.140", :auth_failed}}

109.77.148.140 = IP of the Cloudron server

Do you think I need to create a distinct mailbox in Cloudron and connect it to Keila instead ?
Thanks

Hello @mononym
Currently, there is an issue with the Keila shared mailer admin ui.
See: https://github.com/pentacent/keila/issues/501
@brutalbirdie did write a PR to fix the issue https://github.com/pentacent/keila/pull/509

Without this fix you have to setup the mailer for the campaign.
To get the credentials from the Cloudron App, open the Web Terminal and run:

printenv | grep -i "CLOUDRON_MAIL"

This will give you all the details.

Example mailer setup:

Hello @mononym
The Keila app has the sendmail addon.
This means automatic mail configuration is included.

But I can see no default shared sender is configured on app installation which makes it confusing when setting up a campaign for the first time.
I will look into it.

I saw that error after I started this thread. My guess was that it wasn't implemented yet as the app is marked as unstable.

That works perfectly, thanks !

Hi,

This is a bug report (except if I missed something!):

• create a new Keila instance
• log in with the generic admin account (admin@cloudron.local)
• head to the "Senders" menu
• there's a button to create a shared sender. Clicking on that button triggers a server error

I tried increasing the allocated resources for the app, but no change.
Thanks
