blocking top-level-domains?
Hello.
we receive lot of spam mails from top level domain .ru
i am using a blacklist but the domains are always different.
i think about blocking all email with .ru ending - the whole top-level-domain
has someone already tried to block a top-level-domain?
is this a good idea or didn`t i consider anything?
how to configure postfix to make postfix blocking all .ru domains?
Thanks
Libor
