Hi,
I've done some debugging and attached are (parts) of 2 strace files.
correct.txt. This is when I click on a folder in Outlook and everything is OK (no headers are retrieved etc.)
wrong.txt. This is when I click on a folder in Outlook and it starts retrieving all the headers again.
Im not sure what to look for in these files.
Cheers,
Jan

Hi,
Here's the dovecot -n output:

I am a bit hesitative for debugging on production I will try and see if can set up some sort of test env. to debug.
Cheers,

Hi Jan,
We run 1.1.3 and I use Outlook to connect to my IMAP box and a couple of times per day (randomly) when I click certain folders IMAP will start retrieving ALL headers for that folder again ('retrieving new headers')!
I don't understand this. What triggers IMAP to do so, why not just retrieve only the NEW headers?
Is it Dovecot or Outlook (probably) and what can be done about this? I already use the Dovecot Outlook workarounds.
I have also gotten word that this behavior happens with Thunderbird.
This is really a problem causing a lot of load on our storage (I am not

Please give us some more information. Output of dovecot -n would be a good
start. Also check the logs for dovecot reporting problems (and/or switch on
debug logging).
