Hi,

I recently had a need to re-install hMailServer, and restore the configuration. That all seems to have worked ok.

I can log into existing hMailServer accounts from Roundcube (v1.6.15) without any issues. hMailServer log:

However, if I try to create a new hMailServer email account and log into that account from Roundcube I get a hMailServer 'Login failed' error:

Any ideas???

Edit: Ahh. Here's the clue I needed. This is from the Roundcube error log, which is where I should have started. d'oh:

[17-Jun-2026 14:38:11 +0000]: <287gkoap> PHP Error: Access denied for new user [email protected]. 'auto_create_user' is disabled in /var/www/html/webmail/program/include/rcmail.php on line 824 (POST /?_task=login&_action=login)
Found the key in config.inc.php and changed it from false to true:

// Automatically register user in Roundcube database on successful (IMAP) logon.
// Set to false if only registered users should be allowed to the webmail.
// Note: If disabled you have to create records in Roundcube users table by yourself.
// Note: Roundcube does not manage/create users on a mail server.
$config['auto_create_user'] = true;
...and we're back in action. No idea when this got changed!

Thanks
Ken.

From your screenshot it looks like you are using a custom skin. 1.7 brought some significant changes to the Roundcube backend, particularly the mandatory use of `public_html/` and the addition of `static.php` for loading assets.

What version did you upgrade from? What is the URL of the logo and what is the exact response from your server? How is this URL set (are you using the `skin_logo` config option or is it defined in the template file)? Do you have any specific config in your web server related to Roundcube? Are all the other assets loading ok, for example once you login does the system work?

I saw you created an issue on GitHub but there is no description of a bug or any problem with Roundcube code, it looks more like a support request so please either add some detail about where you think there is a bug in Roundcube code or close it.

I'm running an ubuntu 24.04 Lemp server, and just tried to upgrade my roundcube version to 1.7.1-complete. The upgrade seemed to go just fine without any errors. However, when I go to the roundcube web address at mail.example.com, the login page shows a question mark where the logo should be, and it seems like the logo is not loading. Please see the uploaded image.

How can I fix this?

Can Split screen be reset up to only have ONE pane?

Do you have an example of a message that causes the problem? May be its related to this issue https://github.com/roundcube/roundcubemail/issues/10198 ? There is a workaround mentioned in the ticket so may be give that a try.

Please contact your email provider or who ever is responsible for the Roundcube installation you are using for support.

Hi,

I am using roundcubemail v1.7.1.1 on Rocky.
Some clients get the mentioned failure when sending mails.
The error is:
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

  [email protected]
    (generated from [email protected])
    message has lines too long for transport

Is there a configuration to configure automatic- linebreaks on webmail installations?

best regards

Iodok

I am using the internet and using the webmail link which i use from my desk top but its not logging me in. I have never had this issue before does this make sense?

Roundcube is open source webmail software it is not a service. If you have problems with your email account (e.g. cannot log in, emails got lost, etc.) or if you have questions how to configure your Outlook or mobile phone to get email, please contact your email provider for support.

Hi Hoping someone can help, i am unable to now log in to my emails via my iphone 17 pro max. I have always used google chrome and log in out of work hours to access my emails. Its now just flashing on the screen when i use my log in details and nothing is happening, i have changed my password cleared search history etc but it wont work. It works as normal from my desktop in the office.
