Hi Stevan,
Hello Eric,
I sent the email you requested to your private email account in a zip
file.
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.
Thanks!
Eric

It would also be interesting to what 'dspam --client' does with this
email.

There have been reports on problems with dot stuffing in the past.
It's a lot more logical that you're seeing those problems too, and not
something related to your attachment.

Hi Tom,
Thanks for your reply.
The following command:
# cat 'email' | dspam --client --user user@domain --stdout
--deliver=innocent,spam
also truncates the email.
