Title: Issues logging in to hMailSever
Post by: chaser on June 17, 2026, 10:25:13 AM
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:

Code Select
[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:

Code Select
// 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.
