I don't really remember why I did it this way, but this works for me.
I'm using it this way because I first check the mail for spam in an ACL.
If it is SPAM, I want to run it through SA again (yeah, I have to many
CPU-cycles to burn :P) to create the report. Anyway, this is how I do
it:

transport_filter = /bin/sh -c '${if eq{$acl_m2}{spam}{/usr/bin/spamc
-U /var/run/spamd.sock -u $acl_m1}{/bin/cat}}'
