Accepting some unknown sender domains

[gobris]

Hello,
While i was examining log , i noticed the following bounce email on my logs..

mail.xxxx.gov[xxx.xxx.xxx.xxx]: 450 4.1.8 <abone-bounces@info.ggm.bim>: Sender address rejected: Domain not found; from=<abone-bounces@info.ggm.bim> to=<info@xxx.net> proto=ESMTP helo=<mail.xxx.gov>

replaced real add with xxx

The problem is this user not a spam user, and it is an important govermental institution that we need to get mail.
It seems impossible to find the system admin of them and correct the bounce domain address...u know government..

And i dont prefer to disable reject_unknown_domain from postfix configuration..
Can you please show me a way (a kind of whitelist maybe) to allow this specific domain?

Must be the Dutch goverment, they moved to the Cloud

The problem is, every solution is wrong.
1. If you allow unknown domains they will blame you when shit hits the fan.
2. Reject the mail and they will demand that they need this mail, so fix it.

In my view we should reject unknown domains, as the sending party should configure dns properly and not blame someone else.
As a last option you could try nicolas solution to add a score for unknown domains ( and remove the postfix restriction: reject_unknown_domain)
