I'm having troubles with a domain I transferred to DreamHost last week.
When the users open access their webmails, sometimes it show all folder as
subfolders of Inbox. Other times, they are all show as root folders (and
without the "special folder" aspect and behaviours when taking actions like
sending mail, trashing or saving drafts).
When they are show as root folder, when a new draft is saved, "INBOX.Drafts"
is created (separately of Drafts root folder). Same for "INBOX.Sent" and
"INBOX.Trash" for sent and trashed messages.
After logging out and login again some times, the folder inheritance is
restored, without a visible reason.
Drafts root folder is then correctly placed as INBOX.Drafts, and that new
INBOX.Drafts then come to be INBOX.INBOX.Drafts (where INBOX.INBOX is an
unaccessible folder). I have them to manually move all mails from
INBOX.INBOX.Subfolders to their correct places and then delete these
subfolders (INBOX.INBOX is undeletable but disappear as soon as I refresh the
page - looks like it has never been created, but the only the subfolders
This occur only with RoundCube, and cleaning all settings, cache, cookies,
whatever of web browser, or even reinstalling it, do not solve the problem
(actually, it seems that the browser has NOTHING to it - these strange
behaviour of RoundCube is very RANDOM and all browsers I tested are affected,
Chrome, IE, Firefox and Opera). Also, logging through webmail.dfurlan.com.br
or roundcube.dreamhost.com, using both "mbox" or "firstname.lastname@example.org", do
not interfere in the problem. Occur in all cases.
I thought to move all INBOX subfolder to root folders and setting special
folders in the root, but your mail server seems to be a default behaviour of
creating INBOX.Sent folder when sending a mail through IMAP in new accounts
(I do not know if it's your mail server or Thunderbird).
Can't you enforce INBOX. prefix in your Roundcube webmail? I tried to create
a root folder using SquirrelMail and this is now allowed, so enforcing the
prefix in RoundCube should not be a a problem (and already created root
folders - using RC - are correctly show both in RC and SM).
Here's a screenshot of Chrome browser, browsing the same mail account, in 2
computers (my own notebook and my customer's pc, that I'm seeing through
Please, answer ASAP. I may need to take actions to 8 mail accounts, depending
on your answer - and it may be a move back to old server
