this causes a sigpipe error in vdelivermail, and gets feed back into qmail-inject as a signal 13 ( sigpipe ). The causes qmail-inject to think that the child ( vdelivermail ) crashed.

the bad email file has this: > Received: (qmail 3973 invoked by uid 508); 30 Jan 2013 21:11:26 -0000

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.
