[Dovecot] Pocket Outlook weirdness

Hi!

I am trying to access my IMAP server running dovecot from my Pocket PC running PocketOutlook. I observe very strange behavior: it starts to fetch messages from INBOX and shows list them on the screen as it fetches, then all messages disappear from the screen and it says "fetching folders". After the end of update operation it shows me empty list of messages.

Have anybody have seen such problem? In general, are there reports of successful pocket outlook + dovecot users?

Any suggestions are appreciated! I really want to make this thing work.

Sincerely, Vadim
