You apparently missed my reply to your mail; It's in the archives:

https://marc.info/?l=postfix-users=159473514401531=2


 postscreen_blacklist_action (default: ignore)

parameter that was new to me. Setting it to "enforce" or "drop" makes
postscreen reject these connections.


I recomment using enforce. Drop makes clients retry.

This is documented, in http://www.postfix.org/POSTSCREEN_README.html
"The postscreen_blacklist_action parameter specifies the action
that is taken next." And that text links to
http://www.postfix.org/postconf.5.html#postscreen_blacklist_action

parameter that was new to me. Setting it to "enforce" or "drop" makes

Thank you! Setting myorigin = $mydomain solved it. No need to alias

The local user exists as andr...@dualbit.de. What is the problem?

Is it possible to use only the domainpart in users address to deliver mail?


you apparently mean only the localpart, and I think it's not posible.
