[Dovecot] Replication and LAYOUT=fs

[Simon Fraser]

Hello folks,

I have a problem with replication and mail_location with LAYOUT=fs set.

If I set "mail_location = maildir:~/mail" (leaving out the :LAYOUT=fs),
create and populate some mailboxes and subfolders, they all get
replicated. If I start with a clean mail spool and LAYOUT=fs, I can
create some new mailboxes and subfolders but only the inbox is
replicated. Subfolders are ignored.

The users are all in LDAP, and virtual, hence the generic mail_home
format and mail_location being set. The userdb lookup has been told to
return no attributes ("user_attrs = "), but I have also tried it with
requesting 'home' and specifying a default of /mail/spool/%u in the
userdb config. 

The service is perfectly functional as far as a mail client is
concerned: it can access all the folders and messages it expects on the
server that had them added. It's only the replication using LAYOUT=fs
that seems to be troublesome.

Here is `doveconf -n` for the first of the pair of servers (dcot1a and
dcot1b). The configuration on the other is identical except for the
hostname differences.
