Actually qmail-scanner is being bypassed by tcp.smtp.cdb.

Mr. Koch,

This is a problem with vpopmail, not qmail-scanner. If you have compiled your
vpopmail from source then you can find where vpopmail is setting RELAYCLIENT
and RBLSMTPD and add a QMAILQUEUE variable to the mix then recompile EVERYTHING
that relies on vpopmail. This is what we do on our systems.

Otherwise you're pretty much out of luck. I suppose you could also try the
qmail SMTP AUTH patches as a workaround, but you're still going to have to
recompile things (you're just recompiling qmail instead of vpopmail & friends).
