[Pkg-dspam-misc] Bug#383964: Bug: dspam adds additional newline to message body when processed with LMTP

[Daniel Kahn Gillmor]

dspam appears to add a trailing newline to the message body as it
passes through dspam's LMTP processing, regardless of the location of
the dspam signature.

It may also do this in non-LMTP cases, but i have not had a chance to
test any other cases.

I first saw this problem mentioned as debian bug 383964:

  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=383964

Let me know if i can be of any help tracking this down further.

A simple example follows.

Here's an LMTP transaction between MTA and dspam:

and the corresponding LMTP transaction between dspam and its LMTP
