Issue Summary: Multiple Domain Configuration Using Different SMTP and IMAP Servers Not Working as Expected

Description:

I'm setting up Roundcube to handle multiple domains, each with distinct SMTP and IMAP servers. Despite specifying server details in host-specific configuration files, Roundcube defaults to `localhost` for IMAP authentication, leading to login failures.

Main Configuration (`config.inc.php`):

<?php

$config['db_dsnw'] = 'database';

$config['support_url'] = '';

$config['ip_check'] = true;

$config['des_key'] = 'key';

$config['product_name'] = 'Webmail';

// Host-specific configuration
$config['include_host_config'] = array(
  'yash-dj-films-and-studio.is-local.org' => 'ydfs_config.inc.php',
  'codelabworks.is-cool.dev' => 'codelabworks_config.inc.php',
);

$config['mime_types'] = '/usr/home/mycodelab-mail/domains/mycodelab-mail.serv00.net/public_html/config/mime.types';

$config['plugins'] = [
  'acl', 'archive', 'autologout', 'database_attachments', 'filesystem_attachments',
  'jqueryui', 'managesieve', 'markasjunk', 'newmail_notifier', 'password', 
  'reconnect', 'redundant_attachments', 'show_additional_headers', 'userinfo', 
  'vcard_attachments', 'zipdownload'
];

$config['enable_spellcheck'] = true;

Host-Specific Configuration Files:

ydfs_config.inc.php

<?php

$config['smtp_host'] = 'mail8.serv00.com';
$config['imap_host'] = 'mail8.serv00.com';

codelabworks_config.inc.php

<?php

$config['smtp_host'] = 'mail10.serv00.com';
$config['imap_host'] = 'mail10.serv00.com';

Logs Indicating the Issue:

Steps to Reproduce:

1. Configure Roundcube for multiple domains with distinct SMTP and IMAP servers as shown above.
2. Attempt to log in using credentials for each domain.

Expected Behavior:

Roundcube should use the specified IMAP and SMTP servers (`mail8.serv00.com` and `mail10.serv00.com`) rather than defaulting to `localhost`.

Actual Behavior:

Roundcube tries to authenticate against `localhost`, resulting in repeated authentication failures.

Additional Information:

- This issue does not occur when only one domain and its corresponding SMTP/IMAP server are configured.

Request:

I would appreciate assistance in resolving why Roundcube defaults to `localhost` instead of using the specified server configurations for each domain.

hello?

If you create a php file in the Roundcube directory with the following what does it return?
1. <?php echo $_SERVER['HTTP_HOST']; ?><br />
2. <?php echo $_SERVER['SERVER_NAME']; ?><br />
3. <?php echo $_SERVER['SERVER_ADDR']; ?><br />
