Ok, but, is that dangerous? :-?

I don't think the hack is easy, postfix is designed to send worldwide.

The danger I see is that mail will be usually rejected.

Or if the user is a spammer, but then the configuration will not be a 
problem for him - but they don't use linux, I think, or techniques like 
temporarily rejecting emails with try later would fail.
