Just to be sure:

that is qmail-local gets the signal 13 from vdelivermail. Vdelivermail has the pipe to qmail-inject broken when qmail-inject closes the pipe.

Apparently qmail-inject stops processing the input file ( via pipe from
vdelivermail:435 if ( write(write_fd, msgbuf, file_count) == -1 )) at
the bogus line that cant be parsed any further.
Once the pipe is closed by qmail-inject, any further writes will get a
sig-pipe error, and the process ( vdelivermail ) will die, as the signal
processing is set to default ( ie terminate process ).

Somehow, qmail-inject has to process the rest of the file, even if there
are parse errors, or vdelivermail has to recognize that a pipe can
suddenly close up.
