locals and HUP qmail-send
When delivering a message qmail checks the local file first. If the
domain is found there it is assumed that the user is a local user and
qmail will attempt to deliver the message to a local user.
If you use vadddomain to add domains to vpopmail then vpopmail will
handle the changing of qmail files for you.

You guys should take a look at Blackhole. Has Qmail-queue mode and
checking based on user and domain I believe. The HOW-TO has more info on it.
