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.

I tried it with the $run command, but it uis always set to false!
defer condition= ${if match{run{/etc/exim/panama
$sender_address_domain}{NameCheap}{true}{false}}
The docs say:
"If the command succeeds (gives a zero return code) <string1> is expanded
and replaces the entire item; during this expansion, the standard
output/error from the command is in the variable $value. If the command
fails, <string2>, if present, is expanded and used."
