You can add to conf.d/10-mail.conf

first_valid_uid = 1000
last_valid_uid = 2000

You have nobody uid 65534 so make last_valid_uid less than you have in
your /etc/passwd. Same thing with the first_valid_uid just pick first
uid after users start in your /etc/passwd

>I don't know why the user 'nobody' shows up here?  nobody is in the
>/etc/passwd file but he has no group.
