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
