You have not given us a lot to go on. Your host config files are in the same location as the main config file correct? And have the same owner and permissions? If there is nothing in the Rounscube error log you may need to do a bit of code diving to find the answer. This is the code that does the work https://github.com/roundcube/roundcubemail/blob/master/program/lib/Roundcube/rcube_config.php#L261

Hello everyone,

Server: unbuntu 20.04
Mail server: postfix

I am on ubuntu 20.04 with a postfix and postfixadmin for the mutidomain with a database.
Also, I installed Roundcube 1.6.5 with a database.
It works very well for a single domain.

I tried to put Roundcube in multi-domain.
I followed the following tutorial: https://github.com/roundcube/roundcubemail/wiki/Configuration%3A-Multi-Domain-Setup

First, I added the variable $config['include_host_config to the config.inc.php file.
Then I added the lines below:

$config['include_host_config'] = array(
    mail.rdomain1.tld' => 'domain1_config.inc.php',
    mail.domain2.tld' => 'domain2_config.inc.php',
    mail.domain3.tld' => 'domain3_config.inc.php',
);

Then I created one file per domain. But it doesn't work.

Do you have a solution?

Thanks

Alain

Oh, ok then, thank you for your input. I will do that. Cheers!

If you didn't install or setup Roundcube then you wont be able to add a skin you'll need to contact your email provider and ask if they can do it.

No Larry or User Interface skins...
