Sorry I do not have a earlier log.
I change today nothing on my folder structure. But I see on my
smartphone an unreaded mail which I delete short before in IMP.
Maybe thats the ground of the new FOLDERSYNC?

Can we make a diff between the working database and the datebase when
activesync do not work? Can we see something there?
IMAP Server is dovecot of debian squeeze.
