There's nothing you can do, don't forward mail to these domains,
they no longer wish to receive such mail.
You are perhaps expected to implement SRS, ... but I would not
bother.
It turns out it is simply that when you are using postini, and use them
for outbound relay/filtering as well, they expect the 'From' address to
be from our domain... this is just stupid. They require me to add their
netblock to mynetworks (which obviously means I must absolutely and
unequivocally trust *their* servers), but they don't return the favor.
So... now the question is, can I do some kind of sender rewriting magic
to get forwarding working again?
