I got the mail. Tested the result with normal "dspam" and with "dspamc" 
and with "dspam --client". Using plain old "dspam" worked flawlessly 
while using "dspamc" and "dspam --client" resulted in stripping data 
from the mail.

Looking at the mail source the error occurred at line 3 (line numbering 
added by me):

001 has low airflow of 92 cfm for exhaust down low which equates to .4 
cfm/ft2=
002 .
003 <b>I suggest that this ducting be modified before I return. Another 
low duc=

So it is clearly a dot stuffing issue. I don't know who is to blame 
here. Usually the client/sender is supposed to do the dot stuffing. The 
'cut' command is not intelligent enough to do this. A small SED command 
however could do that:
( sed '/^$/q' 'email' ; echo ; sed '1,/^$/d' 'email' | sed 's:^\.$:..:g' 
) | dspamc --user user@domain --stdout --deliver=innocent,spam

I don't know how to intelligently catch this issue in the code (it has 
been a while since I looked or touched the code). IMHO piping data to 
the DSPAM binary should not suffer from this dot stuffing. If you would 
send that directly to LMTP/DLMTP socket then I would say that it is 
clearly your problem but piping? I don't know.
