[Dovecot] isync with dovecot

[tino.keitel at gmx.de]

Hi folks,

I use isync, an IMAP sync tool (Debian package isync 0.9.2-2) together
with dovecot (dovecot-imapd 0.99.10.8-0.backports.org.1).

Everytime when isync wants to upload a new mail from the client to the
server I got messages like this:

Mailbox outbox
Selecting IMAP mailbox... >>> 16 SELECT "outbox"

My concern is the line "IMAP error: incomplete SEARCH response". I
already saw this mesage with old versions of courier-imap, which won't
return an APPENDUID tag so the client doesn't know which UID will be
used for the uploaded message (this was the explanation I got). Is
there any way to get dovecot to return the UID when a message is
uploaded?
