So basically I would like to reject email from all mailservers having
a reverse name lookup matching the pattern *.artegic.net How can I
obtain that?

Add a regular expression client restriction to your restriction list in
main.cf:
smtpd_recipient_restrictions =
...
check_client_access pcre:/etc/postfix/client_access.pcre
...
and define the offending domain in that file:
/\.artegic\.net$/ REJECT Not accepting mail from your domain.
for blocking .artegic.net you don't need to use pcre.
simple hash table containing ".artegic.net" would be faster.
