[Dovecot] Maildir owner importance

[Roi Efrati]

OK, I'v set all the directory tree from the main maildir
(/var/local/virtualdir/) to the virtualmail user using chmod -R
virtualmail.virtualmail /var/local/virtualdir

And correct me if I'm wrong,
The auth_user is still "auth_user = root" and I need to have the
"default_mail_env"
set as default_mail_env = maildir:/var/local/virtualdir/%d/%n .
But I also need to set:
first_valid_uid = 100                                        
last_valid_uid = 100                                         
first_valid_gid = 101                                        
last_valid_gid = 101
which are the uid and gid for the user virtualmail
