You guessed right! QMAILINJECT was indeed set, and it was set to `f'
(see the qmail-inject manpage for details :-). I commented it out and
all the trouble was gone. There's just the Return-Path left to the
MAILUSER and MAILHOST variables, but I don't care much about that. I
think I set QMAILINJECT when I followed some installation instructions
too blindly to know what I was doing.
