Technically, this isn't a valid RFC[2]822 message. There is supposed to
be a blank line between the headers and body of a message even though
most MTAs accept it. I _think_ this is what is causing lmtpd to hang
out. Your timing is good, because I committed a fix for this
yesterday. Try this patch and see if it solves the problem.
