I'm not sure where that address goes, off-hand, but this is probably a
better one.

Hm. I'm not entirely sure what you're seeing here, since it isn't quite
the way that I believe VERPs work. qmail-send translates a return address
of the form:
list-bounces-@host-@[]
to:
list-bounces-recipbox=reciphost@host
and it uses the presence of -@[] to decide whether to do that. The -@[]
string is fixed (hard-coded in qmail-send.c), but the - there shouldn't
matter because it's stripped. The VERP process doesn't appear to add any
other break characters; instead, it uses the characters already in the
address.
So if you just fix whatever it is that you're using to send mail so that
instead of generating return addresses of the form:
list-bounces-@host-@[]
it generates them as:
list+bounces+@host-@[]
I believe you'll immediately get what you want.
