[Dovecot] new mails don't always show

Hi,

I am having some trouble with dovecot (0.99.14) and maildir. Some users
are reporting that sometimes, they don't get (pop3, various clients) new
mails for a while even though they should.
I checked and confirmed this: mails were delivered by MTA (sendmail,
procmail). But when the problem existed, the new mails were in cur/, not
new/ and dovecot would not report any new messaged to the client.

A 'solution' was to send another mail to the same account, and ususally
this would end up in new/
On the next fetch, this new message and the new ones from cur/ are
downloaded.

I also had the same problem with imap and evolution today. My inbox
showed as empty but there were many messages in cur/
I could access all other folders without a problem during this period.
Again, a simple mail to myself 'solved' this.

This behaviour does not happen all the time and I don't know how to
trigger/reproduce it.

Just the relevant (imho) parts of dovecot.conf:

login_process_size = 256
login_processes_count = 64
login_max_logging_users = 1024

default_mail_env = maildir:%h/Maildir

client_workarounds = outlook-idle oe6-fetch-no-newmail
outlook-pop3-no-nuls

everything else is set to default values

Any ideas/help?

Thanks
Bjoern
