As I suspected, this is an MTA issue. Apparently, you have two parallel 
local delivery transports configured. I have no idea how this is 
configured in Qmail and what exactly you may have done wrong.

Although other people on this list probably do have knowledge of Qmail 
configuration, MTA-related questions are mostly off-topic, so you may 
not get an answer here. I suggest you contact the guys at qmail.
