This finaly did the job:
acl_check_mail:
deny condition= ${if match{${run{/etc/exim/panama
$sender_address_domain}}}{NameCheap}{true}{false}}
Now all Spamer from NameCheap are out.
Greetings

Betreff: Re: [exim] Get the value of an external script in a condition
>From the documentation that Jeremy quoted, I think that your script should
use "exit 0" and "exit 1" (or other non-zero value).
Your exim config snippet does not use $value in the match; you need to do
that or do the match in your script and use exit 0 *only if there is a
match*.
Interesting idea to use the whois database to detect spammers.
Since whois data has expiry info and doesn't change every day, I wonder how
easy it would be to cache the results.
whois isn't as easy to script as you may wish (Tony Finch has a rant about
this at
https://fanf.dreamwidth.org/113367.html
) but it may be sufficient for your use.
