I'm trying to run a subdomain as uid/gid 'mail' 
(CGI Scripts in this directory need to run as this uid/gid to avoid chmod'ing some directories 777)
The problem is that any attempt to run cgi as mail results in this error:
emerg: cannot get docroot information (/)
Can't seem to find much information about this.
Login: mail Name: mail
Directory: /var/spool/mail Shell: /sbin/nologin
(Just in case the mail homedir matters)
