Cheers for this tony,
I am trying to get it to check for the null sender address and then do
the verify on the recipient but I just can't get it to work, its failing
on the check for the null sender address and not getting as far as the
verify.
This is my best effort (or worst- haven't decided yet) so far:
deny message = I dont accept mail with a NULL SENDER ADDRESS &
invalid
RECIPIENT ADDRESS
condition = ${if $sender_address = <>}
!verify = recipient/callout=random,10s
Does anyone know about the ndr's going out with no from postmaster
address...

require verify = recipient
or if you are feeling strict,
require verify = recipient/callout
