dovecot - Nov 2008 - expire tool question

Hi, I try to get expire working, with the BDB backend and mbox mailboxes.

If I try to invoke the expire-tool like

 /usr/local/sbin/dovecot --exec-mail ext 
/usr/local/libexec/dovecot/expire-tool --test

I get

[root at m ~]# /usr/local/sbin/dovecot --exec-mail ext 
/usr/local/libexec/dovecot/expire-tool --test
Error: read(/var/run/dovecot/dict-server) failed: Remote disconnected

Hmm. I searched for hints but could not find a related discussion or 
problem.
Here are the relavant config parts:

dict {
  expire = db:/var/lib/dovecot/expire.db
}

plugin {
# expire plugin
expire_dict = proxy::expire
expire = backup 7 spam 30
# If you have a non-default path to auth-master, set also:
auth_socket_path = /var/run/dovecot/auth-master
}


Any ideas? Has anybody got this working ? The file 
/var/lib/dovecot/expire.db doas not exit even though I restarted DC 
quite a while ago.

Regards,
Jakob

My first finding is that I need to enable db when doing ./configure. Now 
I see a berkeley database tree in the /var/run/dovecot/ directory.
However this has the timestamp of the last restart and does not change 
even when I access one of my expire-configured folders (backu and spam).
Should the DB not be updated every time I access one of these folders? I 
have no namespaces and the folders are directly in the user's home dirs.

But at least the expire-tool now runs silently. Totally silently. No 
output at all....

Comments welcome.
