[Dovecot] expire plugin - setgid failed

[e-frog]

You are right. When I unset HOME before running expire-tool I don't get 
the error message. I'm not sure how to add a user to the expire 
database. All I configured is using passwd as userdb. I have include my 
configuration below:

root at server:/var/lib/dovecot# dovecot -n
# 1.1.rc8: /etc/dovecot.conf
