While debugging a different problem, I used "doveadm dump" to show information about a maildir folder; it happily reported values from dovecot.index and dovecot.index.log (confirmed by strace):

[...] messages count ........... = 978 seen messages count ...... = 967 [...]

However, mail clients reported different values, I guess because the Seen flags were actually stored in the dovecot.index.pvt.log files.

Is this a known problem or a result of my (maybe unsupported?) setup?

My public maildir folder contains only links to mailboxes of the private maildir of the mail admin, i.e.:

/home/vmail/public/.Info -> ../adwin.de/mail-admin/Maildir/.Info

namespace { list = children location = maildir:/home/vmail/public:INDEXPVT=/home/vmail/adwin.de/%n/public prefix = ADwin/ separator = / subscriptions = no type = public }

My setups leads to .pvt-files in the public namespace, could this be a problem? http://wiki2.dovecot.org/SharedMailboxes/Symlinks explicitly states that symlinking _should_ work.

Using version 2.2.13 (debian packages).
