With the EXIM4 exiscan strategy, spamassassin only gives the score and the
hits required. I have a request to set up an alias "spamcheck" which would
do effectively
cat message | /usr/bin/spamassassin |mail -s SpamCheck sender
(this works when I put myself as sender)
I have tried to do this via a ".forward" file with PIPE but so far have
failed (account below)
Does anyone know how to do this via EXIM?
What I think would like, is the ability to include the current output from
a pipe as the message body in an EXIM filter MAIL command with the ability
to ignore PIPE non-zero return values.

=================================================================A
Long account of failure.
What I have done is set up a special
spamcheck:
driver = redirect
condition = ${if eq {$local_part}{spamcheck} {1}{0} }
file = /etc/exim/spamcheck
no_expn
user = mailnull
allow_filter
file_transport = address_file
pipe_transport = address_pipe
reply_transport
(had to remove no_vrfy as spamcheck is not in the system alias file)
where the file spamcheck is
# EXIM filter
# spamchecker
pipe "/usr/bin/spamassassin | /bin/mail -s SpamCheck $sender_address"
and the address pipe is
address_pipe:
driver = pipe
user = mailnull
allow_commands = /usr/bin/spamassassin : /bin/mail
Running EXIM with -bt d+all. part of the log gives
address_pipe:
driver = pipe
user = mailnull
allow_commands = /etc/exim/spam.sh

Looks ok so far!
However sending a message to it gives the following log file
