As suggested earlier, I deleted all .imap directories and the log sync errors stopped - for a while.
They have now returned. It seems to happen for every mailbox that gets accessed.
Dovecot version 2.1.1 with pidgeonhole 3.0.0 on Mandriva Linux.
Could this interfere with sieve filters? Several users have filters but none of them seem to do anything.
