I will give one example of why it is not safe: Postfix accepts mail into the queue and then bounces it later. When this bounce is blocked by a filter, it will disappear into a black hole, which violates the SMTP standard. That is only one example; that is sufficient to demonstrate that something is unsafe. Showing that something is safe requires a more detailed analysis. I have no time for that.
Ok, I understand that you don't have time to explain Postfix internals but the subject was regarding documentation and the MILTER_README is wrong. And btw, if you think that blocking bounces is evil ( not saying you are not right ), check the EXAMPLES section in http://www.postfix.org/header_checks.5.html. José Borges Ferreira
