Ok, this is a solution. I tried to avoid this because it consumes some
resources.
I have problems ONLY with this specific spam.
I try to find out if there is something like this:
- reject all emails that come from a different server to my server and
have the From: header a local address (on my server).
In /etc/posfix/access_sender I have:
mydomain REJECT Illegal domain
I doesn't work.

To block mail during the SMTP session, you need to configure Postfix
with a before-queue filter such as amavisd-new which can integrate
SpamAssassin into Postfix.
