setuidgid fatal unknown account qmail

[PM Martin]

This is the error message I get when I start up qmail from the startup
script. I have installed the daemontools and tcpserver, but it just goes
into
an infinite loop, when qmail script is started, though qmail is running
okay.
Please help. I have read all the docs, and faqs, searched archives, and
tried and retried...am running out of hair to pull.
