[Dovecot] Maildir owner importance

[Roi Efrati]

I'v changed the 'auth_user' to 'dovecot' and it have a uid/gid lower then 100.
Does the the virtualmail user need to have a shell account ? Do I have
to change the last_valid_uid/gid to the dovecot user or leave them on
the virtualmail user ?
Are there some settings in the dovecot.conf file that I need to check
that they will not be there ?

The plan is to use Dovecot with pam&mysql.  (Expect quextions soon).
