Policy server returns

[Rod K]

As I understand it Postfix only allows a single line return from a 
policy server.

e.g. this is valid:
REJECT Because I want to\n\n

but this is not:

PREPEND X-MYHEADER: this is my added header\nDUNNO\n\n

If that is the case I want to clarify that a PREPEND or REDIRECT reply 
will result as a DUNNO as far as later processing.

Thanks
