so lessee what happened:
- I composed a message to postmaster@ your domain
- your server "greylisted" it
- my postfix retried
- your server sent the temp fail that I posted

so my server was considered "spamming" just because my postfix retried.

now, since I didn't click on your CR link, I am "found spammer"?

c'est une logique implacable ;-p

I have news for you: every time I send a message, millions of spam
messages are sent at the same time. and obviously, a lot hit each server.

no need to be sorry. it's you who have a problem.

as you certainly noticed, your CC message was rejected. This is a local
policy ("challenge-response will not be tolerated").

if you want to reach me, try sending from another place, using another
sender domain (no challenge-response).

There are a lot of anti-spam methods out there. many that are effective
and not abusive/annoying.

if you ask this question, then the best I can tell you is: outsource
your mail filtering.

fighting spam requires time and resources. if you're motivated, start by
using zen.spamhaus.org. then search the web for other measures.
