[Dovecot] expire tool in 1.1.11

Hi,

I am on dovecot 1.1.11 trying to figure out the expire tool ....

The thing is that when I had confed the exp tool there where a bunch of mails inside the mail boxes. Thus it seems as if the database is not updated about them. Is there a way to update it from command line to include the old mails ???

Thanks Harry
