I upgraded to dovecot 2

doveadm expunge -u wells@thedarktimes.us mailbox Trash savedbefore 7d
     This does not work

doveadm expunge -u wells@thedarktimes.us mailbox Trash savedbefore 0d
     This does work, however it removes everything

doveadm search -A mailbox Trash savedbefore 0d
     This does not work

doveadm search -A mailbox Trash savedbefore 0d
     This does work

any dovecot command with a savedbefore doesn't seem to work

Troubleshooting:

(a)
I have a expire table in the vmail database, I check the time_stamp and it looked correct, showed in the past.

(b)
doveadm fetch -u wells@thedarktimes.us date.saved mailbox Trash 1
date.saved: 2012-05-23 13:21:42
I think this is suppose to be the oldest deleted email?
If so, this is wrong

(c)
deleted the expire table and recreated it

mysql -u root -p
use vmail;
CREATE TABLE expires ( username varchar(75) not null, mailbox varchar(255) not null, expire_stamp integer not null,  primary key (username, mailbox) );   

(d)
now the expire table doesn't populate when I delete emails (this is a problem)

(e)
added to dovecot.conf
mail_plugins = $mail_plugins expire
and under each protocol, mail_plugins expire

/etc/dovecot/dovecot-dict-expire.conf
connect = host=127.0.0.1 dbname=vmail user=vmail password=**********************

  pattern = shared/expire/$user/$mailbox
