I have a multiserver setting, with the ISP console on server1, the mail server on server2 and the database server on server3. I can access Roundcube with https://server1:8080/webmail, but when I enter the loggin of an user, I get a "Connection to storage server failed" error. The remote user "roundcube" is created in the ISP console. In the set up, which server is the "storage server"? And, of course, how can I get a connection to it for the users?
from a quick search for the string 'storage server' in /var/lib/roundcube/, it appears to be the imap server. I believe just set $config['default_host'] in rouncube's config file.
Well, I tried all possible configuration for roundcube but nothing works. Since it's a basic multi-server set up, I'm surprised that nobody else face the same issue.
Ensure that you set the hostname of the mail server as imap and smtp server in the roundcube config file and that no firewall blocks access to it. storage server is not related to ispconfig nor remote users.
