Could you explain exactly WHY you need vpopmail? It's a very common 
mistake to think that Qmail don't handle virtual domains without it, but 
in fact IT DOES. Vpopmail does 2 things: 1/ doing that stupid virtual 
domain stuff which is not needed, and 2/ an alternative auth thing that 
is not needed as well when you see the number of alternative 
checkpassword binaries available. I really think that vpopmail survives 
only because many think it's needed, because of the bad advertising 
Inter7 is doing, which I think is a very silly stuff. I just hope that 
no MLMMJ patch will break my vpopmail-free configuration.

Under my configuration it's:
user@domain.tld -> domain-tld-user@domain.tld

In fact, it could be:
user@domain.tld -> what-ever-you-like-user@domain.tld

as Qmail permit it using the virtualdomains configuration file.

I'm happy to learn that.

Can it be used WITHOUT vpopmail? IMHO it shouldn't be REQUIRED.

I DO use the preline in the binary I use, and it works !!! Here is my 
.qmail-default file content:

|preline -f /usr/bin/mlmmj-recieve -L 
/var/www/sites/dtc/gplhost.sg/lists/gplhost.sg_dtcdev
