Hello,
 
I've got a server with courier-imap on it (qmail / vpopmail / courier-imap).
 
My directory structure is (for user 'user' on domain 'example.com') :
 
/home/vpopmail/domains/example.com/user/Maildir/cur
/home/vpopmail/domains/example.com/user/Maildir/new
/home/vpopmail/domains/example.com/user/Maildir/tmp
/home/vpopmail/domains/example.com/user/Maildir/.Sent/cur
/home/vpopmail/domains/example.com/user/Maildir/.Sent/new
/home/vpopmail/domains/example.com/user/Maildir/.Sent/tmp
/home/vpopmail/domains/example.com/user/Maildir/.Trash/cur
/home/vpopmail/domains/example.com/user/Maildir/.Trash/new
/home/vpopmail/domains/example.com/user/Maildir/.Trash/tmp
 
Which settings must I apply to roundcube for it works ?
 
(imap_root, sent_mbox, trash_mbox, default_imap_folders, mail_header_delimiter, ...)
 
Thanks for your help !
Steph
