Please forgive me if this has been answered somewhere, I did my best to find out before posting.
Does RoundCube store it's IMAP email in the MySQL database or reference it in the Maildir directories used by Qmail?
Basically, I do not want to have to double my disk space usage for my users by having the email in the both the IMAP accessible Maildir directories and the MySQL RoundCube database.
Thanks in advance for any info!
