On some systems there are commands that make this easy. Solaris and
Linux:

   # groupadd nofiles
   # useradd -g nofiles -d /var/qmail/alias alias
   # useradd -g nofiles -d /var/qmail qmaild
   # useradd -g nofiles -d /var/qmail qmaill
   # useradd -g nofiles -d /var/qmail qmailp
   # groupadd qmail
   # useradd -g qmail -d /var/qmail qmailq
   # useradd -g qmail -d /var/qmail qmailr
   # useradd -g qmail -d /var/qmail qmails
