Thanks that solved that

and indeed my training message is piped through as I hoped.

I now moved that same script to replace the call to dspam in master.cf 
of my postfix config to check how that was being called for retraining, 
and indeed it is
being called

/usr/bin/dspam --client --mode=teft --class=spam --source=error --user 
alan at chandlerfamily.org.uk

with the correct message on the standard input.

HOWEVER  the following appears in syslog when revert all the changes to 
the proper programs

Mar 12 22:09:54 piserver dspam[21941]: Unable to find a valid signature. 
Aborting.
Mar 12 22:09:54 piserver dspam[21941]: process_message returned error 
-5.  dropping message.

Any idea why dspam can't find the signature.
