Change qmail-smtpd to run as the vpopmail user and it should Just Work.
But he's using the old patch (it requires a hostname as the first arg to qmail-smtpd) which isn't compatible with vpopmail 5.4.x.
Use the fehcom patch. Either the latest version from Erwin's site, or the older one included in vpopmail's contrib directory.
