Hi,
I've recently migrated my emails from a Yahoo account to my own
mailserver on a VPS.
Ever since then, Thunderbird seems to have issues with the mailbox's
directory structure: When I start Thunderbird, it immediately deletes
the local copies of all 3rd-level folders (i.e. subfolders of a
subfolder of a folder in the mailbox root).
Since that didn't happen with the Yahoo account, I assume it's some kind
of error or misconfiguration of Dovecot.
Here's an example of the mailbox structure:
voidptr.de
'-> University
'-> IEEE
'-> Conference
"University" and "IEEE" work without problems, but "Conference" gets
deleted locally every time I start Thunderbird. When I collapse and
re-expand "University" in the folder panel, all subfolders (including
"Conference") reappear, but Thunderbird has to re-download the contents
of "Conference", since it deleted the local copies earlier.
It looks as if Dovecot only reported the topmost two folder levels when
Thunderbird requests a folder list...
Is there any way I can change that behavior?

why LAYOUT=fs ?, try without

Directory Structure
By default Dovecot uses Maildir++ directory layout for organizing
mailbox directories. This means that all the folders are directly inside
~/Maildir directory:
~/Maildir/new, ~/Maildir/cur and ~/Maildir/tmp directories contain
the messages for INBOX. The tmp directory is used during delivery, new
messages arrive in new and read shall be moved to cur by the clients.
~/Maildir/.folder/ is a mailbox folder

~/Maildir/.folder.subfolder/ is a subfolder of a folder (ie.
"folder/subfolder")
You can also optionally use the "fs" layout by appending :LAYOUT=fs to
mail_location. This makes the folder structure look like:
~/Maildir/new, ~/Maildir/cur and ~/Maildir/tmp directories contain
the messages for INBOX, just like with Maildir++.
~/Maildir/folder/ is a mailbox folder

~/Maildir/folder/subfolder/ is a subfolder of a folder

Thunderbird
If you're using mbox, dbox or Maildir with :LAYOUT=fs ,

    You should enable tb-extra-mailbox-sep workaround for IMAP.
