I have, once a day or so.

I am using mbox and Dovecot just doesn't seem to write "Status: R" flag
everytime it should. Dovecot has "mbox_lazy_writes" enabled by default
so flags are written only at closing of mailbox, but as it seems for some
reason it doesn't always happen. Since I'm using Dovecot LDA I thought to
disable "mbox_lazy_writes" because on LDA stored mail there is padding in
the message headers so immediate flag writes won't generate much writes at
all, I did this yesterday so I cannot say yet for sure if it fixed the
problem or not.
