That doesn't look like qmail, but maybe you've just got a patched up version.
What SMTP AUTH patch did you use, and what does your qmail-smtpd/run file look like?
If it has "/home/vpopmail/bin/vchkpw hostname /bin/true" in it, try removing the hostname. It was necessary in older SMTP AUTH patches, but creates an open relay with the newer patches.
