My maildir folders are stored as follows: /var/spool/virtualmailboxes/mydomain.com/mails/{username}/ e.g. for a user named john /var/spool/virtualmailboxes/mydomain.com/mails/john/ How would I configure my servers.php file to accomodate this setup? I see where I should define this in servers.php, How would I define this 'folders' => 'mail/',
