Well I am STILL struggling with this.

here is my (revised) plugin parameters (and also a temp change to call a 
script rather than sendmail)

     antispam_debug_target = syslog
     antispam_verbose_debug = 1
     antispam_backend = pipe
     antispam_signature = X-DSPAM-Signature
     antispam_signature_missing = error
     antispam_trash = Trash
     antispam_spam = Junk
     antispam_allow_append_to_spam = yes
     antispam_pipe_program=/home/pi/callsendmail
     antispam_pipe_program_args=-f;dspam at chandlerfamily.org.uk
     antispam_pipe_program_spam_args=%u at spam.spam
     antispam_pipe_program_notspam_args=%u at ham.ham

To try and find out what is going wrong.

the /home/pi/callsendmail script has the following in it

#!/bin/sh
echo "$$-start ($*)" >> /tmp/dspam-train.log
cat<&0 >> tmp/dspam-train.log
echo "$$-end" >> /tmp/dspam-train.log

exit 0

So I was hoping to see my training message in the log.  Instead I just 
get this

21536-start (-f dspam at chandlerfamily.org.uk alan at spam.spam)
21536-end

Is it my shell script that is wrong or antispam - why is nothing written 
in my log file?
