Thanks, in my previous tests I didn't use quota plugin with deliver which was needed to notice this. The problem is:

1. deliver adds "message appended" to index file
2. quota plugin runs for a while
3. deliver updates filename<->uid mapping in dovecot-uidlist

Thanks for the quick answer.

Why does it take four seconds (!) from the time dovecot first reports an invalid message information until the correct information is reported? The time is measured for the delivery of a 1KB message to an empty mailbox on a completely idle system.
