Really the only way to solve this properly is to stop providing relay
service. Relay service is a non-op in the current spam war. If you
do what you are trying to do here, then legitimate bounce messages
will also be dropped and thus you'll be decreasing the quality of
their service. (and if you don't, you'll be creating backscatter)
It's a no-win scenario. If they do their own spam scanning, they
should accept the mail directly.

In our company we have the (mailer-exchange -> spam-scanner ->
customers
with their own mail servers) topology.
We relay mail to them but some of them don't have the spam service
with us
and prefer to have it on their side, then we are all the time
getting the
spam we forward rejected, our spam server generates a bounce (From:
[EMAIL PROTECTED] (Mail Delivery System)).
This bounce keeps bouncing there until expires increasing the load
of our
server.
We would like to know if there is any way to force the filtering
the mails
from [EMAIL PROTECTED]
As far, the only guess i found was to modify the master.cf somehow
from
this:
smtp inet n - - - - smtpd -o
content_filter=smtp:[127.0.0.1]:10024
localhost:10025 inet n - n - -
smtpd -o
content_filter=
To something like this
smtp inet n - - - - smtpd -o
content_filter=smtp:[127.0.0.1]:10024
localhost:25 inet n - - - -
smtpd -o
content_filter=smtp:[127.0.0.1]:10024
localhost:10025 inet n - - - -
smtpd -o
content_filter=smtp:[127.0.0.1]:10024
Filtering the localhost generated mails.
But I donno if it's the right approach.
Any help appreciated
Cheers
