Let's say im trying to block a country tld (say .nl or .ru)
I tried adding *.nl to postfix blacklist in ISPCONFIG3. somehow the mail still gets delivered.
But if i do block an adres like this it works: firstname.lastname@example.org
but doing @domain.ru doesnt nor does *@domain.ru
anythoughts on this ? Or should i use regex better in this matter ?
Thanks ! RObbert
