Sorry, couldn't resist this: read my email more carefully :-)

"Unfortunately I then read through the BUGS section and found this: "Many  
people  overlook  the main limitations of header and body_checks rules.  
These rules  operate  on  one  logical message  header or one body line at a
time..."

So, my question to the list therefore is, does anyone know a way of doing
this, preferably without modifying postfix?"

Best,

Adam.
