Re: [PLUG] spamassassin help: create a rule to score by sender TLD


Have you considered that;
It is not the new TLD's that are flooding your users in boxes with spam?

Have you spent the time and analized the IP numbers and actual
servers / isp's that are attacking you?

You do understand that you have to have an IP number to send an email?

You do understand, as you yourself has two names per your one ip
number, that you can have a gazillion names on a single IP number?

Have you considered that the TLD's you are blocking may be the target
of a denial of service?

Why are you not thinking about punishing the actual senders of your

have you instituted any dnsbl?

many dnsbl, for example SpamCop operates transparently 

The spammers hide as anti spam activists, sometimes in plain sight. 

They like confusing issues and misquoting and saying all sorts of warm
fuzzy things, but there is one simple truth:

An IP number is used to deliver email to you

The server/ip admin / criminal / whatever should be punished...

What some very large companies are doing is they use the same IP
number ranges to transmit valid and legit emails as they use to earn
money from email marketing

So, when you "block" a tld, it only serves to make the spammers stronger.
