[Dovecot] dsyncing lazy_expunge namespace

[Angel L. Mateo]

Hello,

	I'm in the process of migrating mailbox from one dovecot server running 
dovecot 2.1.9 with mailboxes stored in maildir format to a newer one 
running 2.1.16 with mailboxes stored in mdbox format.

	To migrate mailboxes I'm using dsync as explained at 
http://wiki2.dovecot.org/Tools/Dsync. The command I'm running in the 
newer server is:

sudo dsync -o mailbox_list_index=no mirror -R -u <user> imapc:

	The mailbox of the user is correctly synced to the newer server, except 
the lazy_expunge namespace, which is not synced at all.

	The config in my old server is:

namespace {
#  hidden = yes
#  list = no
   # Temporally, only for migration
   hidden = no
   list = yes
   location = maildir:~/Maildir/expunged
   prefix = BORRADOS.
   separator = .
}

	and in the newer one is:

namespace {
   hidden = yes
   list = no
   location = mdbox:%h/expunged:INDEX=/mail/indexes/%2Ln/%Ln/expunged
   prefix = BORRADOS/
   separator = /
}

	With a tcpdump I have checked that old servers list the namefolder, 
this is the IMAP dialog for an example user:

* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE

* STATUS "SPAM" (UIDNEXT 3 UIDVALIDITY 1316372649)
4 OK Status completed.
5 EXAMINE "SPAM"

...

	But "BORRADOS" is never selected in the rest of the dialog.

	Any idea?
