OK, this should be good:

Right?
No. All the backup MX servers must be in internal_networks too
I know, that smtp auth often solves many problems, but today I cannot
force all our clients to use it. So that means, that someone uses it,
but mostly not.
you should add all clients that do not use smtp authentication to your
trusted_networks. Note that this will make it harder to detect spam
they will send to you.
hope that helps, if not post sample on pastebin, and just mangle
sender donain with example.org
But there is still the question what bad happened when DOS_OE_TO_MX
matched the message?
because the client used outlook express and has sent mail directly to
destination (your) server. Mail clients should use SMTP servers for
sending e-mail. That's why you need to use SMTP authentication or
trusted_networks - to let SA know it's not spamming MUA from outside
spamming your network.
