Hello, I am begineer to roundcube. Please help me, I have difficulty to integrate roundcube to my existing email database. For your information, I use Freebsd operating system, with Exim and Courier-Imap. I use vexim to create my database email. But in roundcube instalation, it ask you to create a new database and must be initiate from its mysql tool. Can you tell me how to make roundcube use my mail database. I cannot login to roundcube. Thank you.

RoundCube needs a database to store contacts and other settings, it access the email using IMAP.
