OK, damed :)

This does interest me!

I got a look at the doc and the use of the policy bank feature. Even with
the examples I didn't get it to work. I don't see how to "bind" a policy to
a specific address. The examples tell me about a port-binding but no
ip-binding.
Also, I think the MYNETS bank policy doesn't fit my needs since I need to
allow special treatment for emails sent out from 127.0.0.1 (which is part of
MYNETS, if I understood correctly) but this would allow the same behavior
for all the other members of MYNETS (my internal network...) which I don't
want...

Any clues?

Thanks
Paulo
