[Pkg-dspam-misc] Bug#688853: dspam: long line in message body causes '530 5.2.0 Message is empty. Aborting.'

'Broken pipe' error occurs in Exim because Dspam just drops connection 
while Exim trying to send data to the socket though 530 reply occurs 
also. I don't know whether this is the SMTP RFC rules? And this behavior 
causes delay and retries to send email to the other Dspam users.
