Thank you, Timo, running dovecot with this changeset, \Seen stored perfectly. Only problems I saw were like:

deliver(listuser): Aug 04 16:06:38 Error: Corrupted transaction log file /home/vmail/listuser/Maildir/index/.INBOX/dovecot.index.log: hdr.size too large (75497472) ... dovecot: Aug 04 16:07:31 Error: IMAP(listuser): Corrupted transaction log file /home/vmail/listuser/Maildir/index/.INBOX/dovecot.index.log: duplicate transaction log sequence (2)

and after deleting dovecot.index.log files they were rebuilt. And I can not see any other problem.

This problem is apparently about changeset http://hg.dovecot.org/dovecot-1.1/rev/eec74a6ad62e .

OK, changed, see if this helps: http://hg.dovecot.org/dovecot-1.1/rev/b5388b21c4c2
